摘要： A fluorescent lamp (L) is disposed in the proximity of a light incidence surface (2) of a scattering light guide plate (1). A prism sheet (4') equipped on each surface thereof with a line of prism elements or lens elements is disposed outside a light take-out surface (5). The angles of inclination of slope surfaces (4a and 4b) satisfy the relation oa > ob. The slope surfaces (4a and 4b) extend in a transverse direction of the scattering light guide plate (1), and slope surfaces (4c and 4d) extend in the longitudinal direction. A reflector (3) is disposed along the back surface (6). Outgoing light from the light take-out surface (5) is efficiently propagated in the direction of the front surface by an inside prism surface and is returned to the inside portion after it is shifted in the transverse direction by an outside prism surface or the lens element surfaces (4c and 4d). The route history of outgoing light from the prism sheet (4') is diversified and visual characteristic can be improved. A peak level of brightness viewed from the direction of the front surface can be improved, while brightness gradually drops away from the peak direction.

摘要： A flat light source having excellent whiteness of its luminance surface and emitting soft light, and a liquid crystal display having high image quality. A relatively thick edge of a light scatter/guide member (1) having a wedged-shaped sectional shape forms a light incidence surface (2). A fluorescent lamp L is disposed in the proximity of the light incidence surface (2), and a silver foil R is so disposed as to encompass the lamp L. A prism sheet (4) is disposed outside the output surface (5) of the light source, and the orientation of the prism sheet (4) is selected so that the direction of lines of prisms coincides with a transverse direction of the light scatter/guide member (1). The direction of the prism surface may be either inward or outward. A prism sheet (8) is disposed between the back (6) of the light scatter/guide member (1) and the reflecting member (silver foil) (3). The prism sheet (8) is disposed in such a manner that its prism surface faces inward. The direction of the prism line formed on the prism surface is selected so that the direction of the lines of prisms coincides with a longitudinal direction of the light scatter/guide member (1).

摘要： A polymer is inserted into a cylinder (1) and heated, and a pressure is then applied to the polymer so as to extrude the same in the shape of a fiber from a nozzle (3). In the meantime, a diffusible material is injected from a nozzle (5) into the central portion of a molten liquid of this polymer through a thin-tube cylinder (4), and it is diffused gradually from the central portion of the molten polymer to the circumferential portion thereof as it flows toward a discharge port of the nozzle (3). The material extruded from the nozzle (3) is air-cooled and taken up around a drum (7) via a roller (6). The fiber-like molded product provides a distribution of refractive index varying continuously from the center thereof toward the circumferential portion thereof, and serves as a convergent or divergent plastic light transmitter. Conversely, even when the molten liquid of the polymer is extruded from the nozzle (5), a light transmitter having a region in which a refractive index varies continuously can be obtained. A proper number of the cylinders and various kinds of materials to be supplied to the cylinders can be selected.

摘要： Provided are an optical resin and an optical member using the same, both orientation birefringence and photoelasticity birefringence of the optical material being deadened and generally eliminated. The optical material consists of a composite constituent system of three or more constituents including a copolymerization system of monomer-element number not samaller than two, combination and constituent ratio of the composite constituent system being set so that both orientation birefringence and photoelasticity birefringence of the optical material are deadened at the same time and 5.0 × 10 -5 or less is given under a condition that principal chains of the copolymerization system have degree of orientation equal to 0.03, and further a photoelasticity constant not greater than 1.0 × 10 -12 (Pa -1 ) is obtained. The composite constituent system may contain an additive containing a low molecular weight compound which has an anisotropic polarizability and can be orientated in a polymer. The composite constituent system may consist of a copolymerization system of monomer-element number not smaller than three. Optical members produced by applying molding to the optical hardly show birefringence if external force is applied.

摘要： A method of making an optical resin, in which a polymerization vessel is filled with solution of a mixture including at least one kind of polymeric monomer or a sol of such polymeric monomer and at least one kind of substance whose solubility parameter and refractive index differ from those of a polymer produced by polymerization of said monomer by 7 1/2 (cal/cm3) or under and 0.001 or more, respectively, and, with heating or irradiation of rays of energy from the periphery of the polymerization vessel, polymerization reaction is caused and developed preferentially from a particular part of solution so that concentration gradient in substances different in refractive index may be caused and thus providing a refractive index continuously changing along a specific direction. The polymerization vessel may be composed of such polymer as swelling and dissolving from the inner wall of the vessel into the solution of mixture. An optical transmitter is obtained by applying thermal stretching to said optical resin after completion of polymerization reaction thereof. Further, after-treatment based on crosslinking reaction is applied to said transmitter for improvement in resistance thereof to heat.

摘要： A non-birefringent optical resin material of a combination of a resin material and an inorganic particle material in a relation in which the signs of their birefringences are the same. The inorganic particles are dispersed in a molten resin material and made to coexist therewith. The organic particles and the molten resin material have birefringences of the same signs. The dispersed system is made to flow into a mold (4) through a gate (5). The molten material flows radially and spreads. The velocity vector of the flow has normal components P, R in addition to the straight-ahead component S. The bond chains of the resin material are oriented generally along the velocity vector. The bond chains of the resin material at and near points A, B on the equiphase surface (7) are oriented generally in the direction from the exit of the gate (5) toward points A, B. The flow velocity has a gradient around a particle. As a result, a moment acts, and the major axes of inorganic particles tend to be oriented generally parallel to the equiphase surfaces (6 to 9) of the flow. Therefore, the orientation birefringences of the materials cancel each other as a whole.

摘要： A non-birefringent optical resin material is obtained by forming a transparent matrix out of a polymeric resin having orientation birefringence of a positive or negative sign, adding to the matrix a low molecular substance having orientation birefringence the sign of which is opposite to that of the orientation birefringence of the polymeric resin for the matrix, and offsetting the orientation birefringence of the polymeric resin for the matrix by that of the low molecular substance.

摘要： This apparatus comprises a light entrance surface, a diffused light exit surface, and a diffused light guide of a volume area having a uniform diffusing power. The value E [cm-1], of the effective diffusion illumination parameter of the guide is 0.45 ≤ E ≤ 100. In the correlation functional approximate expression, η (r) = exp [-r/a], expressing the uneven refractive index structue of the guide, the correlation distance a is 0.01 νm ≤ a ≤ 50 νm. No diffusing layer of diffusive ink need to be formed on the back side of the guide. When an element for correcting the direction of the light outgoing from the light exit light surface, having a serrated surface is provided on the light exit surface, it is possible to increase the light traveling in a specific direction. The uneven refractive index structure can be produced by kneading a polymer matrix and a granular material having a different refraction index, by kneading two or more polymers having different refractive indecies, or by dispersing a granular material by suspension polymerization. The material having such a structure is then molded and used as the guide.
