摘要： PROBLEM TO BE SOLVED: To obtain a high numerical aperture by using a transparent resin material having thiol or sulfide bonds to fill recesses on the substrate surface. SOLUTION: Plural recessed parts 7 having the shape of almost a part of sphere or cylinder are arranged in one dimension or two dimensions on the surface of a substrate 6 consisting of a quartz glass or low expansion crystalline glass. These recessed parts 7 are filled with a transparent resin material 8 having a refractive index higher than that of the substrate so that the inside of the recessed parts 7 acts as a convex lens or a lenticular lens. The transparent resin material has thiol (R-S-H) or sulfide bonds (R-S-R'), wherein R, and R' are hydrocarbon groups. The hydrocarbon groups are preferably phenyl groups. As for the high refractive index resin 8, the mixture of polyisocyanate and polythiol (having 1.660 refractive index after hardened) can be used.

摘要： PURPOSE: To provide a liquid crystal display device improved in angle-of- visibility dependance. CONSTITUTION: A liquid crystal cell 1 has liquid crystal 13 filled and held in between two glass boards 11, 12, a stripe transparent electrode 14 formed inside (liquid crystal side) of the glass board 11 on the light source 4 side, a sol-gel layer 15 formed inside of the glass board 12 on the display plane side and a stripe transparent electrode 16 formed on the inside of the sol-gel layer 15. The sol-gel layer 15 is constructed by dispersing in medium 17 grains 18 such as beads with a greater refraction factor than that of the medium, so that light entered into the liquid crystal cell 1 is refracted and dispersed by the grains 18 in the sol-gel layer 15 to improve angle-of-visibility dependance.

摘要： PURPOSE: To improve the effective opening efficiency of a liquid crystal projector television by having the characteristics within the region enclosed by specific dot sets on an X-Y plane having specific coordinates, thereby optimizing the light condensing characteristics of a flat plate lens array. CONSTITUTION: This flat plate lens array is formed by one-dimensionally or two-dimensionally arranging microlenses on a transparent substrate. The flat plate lens array has the characteristics within the region enclosed by the sets of the dots expressed by drop-out circle marks in Fig. on the X-Y plane having (Tsub /nsub )/P as its X coordinates and f/P as its Y coordinates. This region indicates the range of the parameters of flat plate microlenses of which the effective opening efficiency attains 54% (1.5 times) when the aperture area is 36% if, for example, the parallelism of the illumination light is ±4 deg., where (f) is the focal length (wavelength 550mn, in the air) of the microlenses and P is the pitch thereof. Tsub is the thickness from the main plane of the microlenses to the condensing side substrate surface and nsub is the refractive index of the medium.

摘要： PURPOSE:To obtain an optical active matrix of a low loss suitable for gradation expression without malfunction by using an optical waveguide partitioned at the boundary between a transparent substrate and an optical waveguide layer with a metallic film, thereby preventing the malfunction by external light, such as back light of liquid crystal display and illuminating light, and the adverse influence of an increase in off current, etc. CONSTITUTION:Many groove parts are formed on the surface of a glass substrate 101 and the optical waveguide 102 of a staircase refractive index type are formed in these groove parts. The metallic film 105 for shielding the external light from the rear surface of the glass substrate 101 is formed over the entire surface of the groove parts. Window parts 113 disposed on clad layer 117 formed on the surface of the glass substrate 101 and the surfaces of the optical waveguide 102 are formed as the window part 113 to introduce light to a photoconductive material 106 in the upper part of the core 103 of the optical waveguide 102 of the staircase refractive index type. The incident light on the core part 103 of the optical waveguide 102 propagates while repeating total reflection. The light from the outside is shielded by providing the boundary between such transparent substrate 101 and the optical waveguide 102 with the metallic film 105.

摘要： PURPOSE:To provide a method for sticking a plane substrate and a thin plane sheet glass substrate to each other without generating microwaving. CONSTITUTION:This method comprises supplying adhesive resin to one surface of the plane substrate 11 and/or the thin plane sheet glass 1, mating and arranging the substrate 11 and the thin plane sheet glass substrate 12, pressurizing these substrates by pressurizing means 31, 32 to develop the resin 21 held therebetween, then curing the resin, thereby sticking the substrate 11 and the thin plane sheet glass substrate 12 to each other. The development of the resin 21 is executed by pressurizing the substrates via a flat pressurizing surface plate. The curing and sticking of the resin 21 are thereafter executed in the state of completely removing the pressurization. The sticking of the substrates is executed by directly using a static pressure or executing pressurization via a high-polymer elastic material in such a manner that uniform pressurization is executed between at least the substrate 11 and the pressurizing means.

摘要： PURPOSE:To obtain the liquid crystal panel which is useful for liquid crystal projection television and extremely high in the utilization efficiency of illumina tion light. CONSTITUTION:The liquid crystal panel 10 consists of a couple of glass substrates 11, 12 and a liquid crystal layer 13. The lighting-side substrate 11 is manufactured by cementing two microlens array plates 20A and 20B across a transparent adhesive layer so that their lens formation surfaces face each other. The microlens array plates 20A and 20B are constituted by arraying and forming microlenses 21 closely as high-refractive-index areas, which are sectioned in a nearly semicircular or elliptic shape, in a surface-flat soda lime glass plate by an ion exchanging method, and the array pattern and pitch are equalized to those of the pixel opening part 13A of the liquid crystal layer. Consequently. this panel has an NA(numerical aperture) which is substantially twice as large as that when an array plate having lenses sectioned in a semicircular or elliptic shape is used.

摘要： PURPOSE:To facilitate with high accuracy manufacturing of a plate lens array with dense packed structure by performing the coating process in two stages by combining a non-wet type mask and consistent liquid. CONSTITUTION:In the first coating process, the surface of a substrate 1 is coated by means of a mask member 2 which consists of the liquid resistant non-wet type material which is provided with a group of openings 2A of the desired lens arrangement pattern, then the consistent liquid which turns transparent after solidification is coated on this surface. The mask member is removed, and the material 4 which turns transparent after solidification is applied or coated on this surface, and the convex surfaces are expanded in the radial direction by making lamination onto the lens convex surfaces 3 obtained in the first process, and the flat surface parts between the lenses which still remain after completion of the first process are reduced. This constitution allows the plate lens array of the dense packed arrangement where it is difficult to manufacture the plate lens array by the press-molding since the substrate is thin and the respective lens sizes are very small to be manufactured easily with high accuracy.

By this constitution, a maximum condensing effect can be obtained, and the utilizing effect of illumination light can be improved.
