摘要： PROBLEM TO BE SOLVED: To improve the contrast of an image preventing external light from being reflected in addition to that an optical filter using neodymium is conventionally used for the purpose of reinforcing spectral functions of a liquid crystal display and so on so as to improve only color reproducibility of the image. SOLUTION: In the structure, in which a hard coat layer 4 having a mat surface 4a is laminated on the upper surface of a transparent film 3 and an adhesive layer 2 is laminated on the lower surface, thereof, the neodymium is incorporated in either one of these layer, thus the color reproducibility of the image is made excellent when the optical filter is placed on the front surface of the liquid crystal display and so on, and the optical filter is made low in reflectance of the external light. The optical filter is applicable also to a reflection preventing film with an optical interference layer, to a transparent conductive film, a lens film for extending a viewing angle or the like.

摘要： PURPOSE: To provide a spreading and supporting jig for films or sheets capable of surely fixing the films or sheets without wrinkling and keeping the films or sheets applied with tension with a relatively simple construction. CONSTITUTION: This spreading and supporting jig is constituted to spread and support the synthetic resin film 150 or sheet having no self-supporting property in a manner as not to wrinkle and slacken the film or sheet. The jig consists of bending parts 110 which bend to a groove part side in the groove parts and fixing parts 120 which do not bend. The bending parts 110 and the fixing parts 120 form fitting parts 130 fitting to each other via the film 150 or sheet by bending the bending parts 110. The bending part 110 sides of the fitting parts 130 are provided with first pawl parts 136 which spread and support the films 150 or the sheets. The fixing part 120 sides of the fitting parts 130 are provided with first locking parts 133 which have tapered parts 132 and consist of projecting parts meshing with the first pawl parts 136. The first pawl parts 136 spread the film 150 or the sheet by rotating force while holding the film or the sheet with the tapered parts 132 disposed at the fixing parts 120 at the time of spreading and supporting the film 150 or the sheet by bending the bending parts 110. The first pawl parts 136 are so formed as to be locked at the points past the tapered parts 132 described above.

摘要： PURPOSE:To prevent a positional deviation at the central position, by a method wherein a roll-like cut body is precut so as to run along a crest of a ringlike cut groove of the roll-like cut body, main cutting of the ringlike cut groove is performed toward one side end part from the central part, restored to the central part again and after positioning at the central part, cutting is performed toward the opposite end part. CONSTITUTION:Face preparation of a roll-like cut body 1 is performed and a cutting reference face is prepared. Then precutting is performed in accordance with a trough of a linear Fresnel lens of a final molded matter, that is, a crest 103a of a ringlike cut groove 103 on the cut body. In main cutting, cutting is performed up to the central part 101 from an end part 102a of a mold, an edged tool 8 is reversed, positioned and cutting is performed toward the other end part 102b from the central part 101. On this occasion, in the main cutting, it is taken as single cutting where cutting is performed one by one at every pitch. With this method, the mold which is free from a pitch deviation at the central part of the mold and depths 103b of the trough of the cut groove become equal can be obtained.

摘要： PURPOSE:To reduce a white band in a horizontal direction generated due to the stray light of a screen by providing a mat forming processing plane which scatters internal reflected light at a vertical convergence linear Fresnel lens sheet. CONSTITUTION:Light projected from a projector is made incident and refracted on the vertical convergence linear Fresnel lens sheet 14 from the smoothing plane of the vertical convergence linear Fresnel lens sheet 14 via a horizontal convergence linear Fresnel lens sheet 12, and it is emitted from a Fresnel lens part 14B, however, a part of it is reflected on the interface of a lens and the air, then, it goes to return light to the lens sheet. Since such stray light is scattered on the mat forming processing plane 18 when it is reflected again on the incident plane of a base film 14A, a position where it is emitted from the Fresnel lens part 14B to the outside can be expanded, and no local emission of the stray light is prevented from occurring, which makes the light hard to be observed. Therefore, the white band extending in the horizontal direction by the stray light due to the vertical convergence linear Fresnel lens sheet can be eliminated or weakened.

摘要： PURPOSE:To hinder the pitch of joining parts from becoming greater than the other parts by joining screen sheets at the joining parts furnished within the noneffective part where no image light passes. CONSTITUTION:A number of lens elements 11 having light converging characteristic such as lenticular lenses are in line arranged on the light incident side of screen sheets 10A, 10B. A non-light emissive part 12 from which no incident light is emitted, exists in a part on the light emission side of the screen sheets 10A, 10B. A transmission type screen 10 is formed by joining these sheets 10A, 10B at a joining part 17 in triangular column which is provided within a noneffective part where no light passes. That is, the ends of the screen sheets 10A, 10B are cut aslant inward, butted together, and joined by a pressure sensitive sticky agent or an adhesive such as of epoxy or acrylic type, and thus the joint 17 is achieved.

摘要： PURPOSE:To prevent the defect of the shape of light incident lenticular lenses without increasing the pitch of the joint parts, to eliminate the chipping, peeling, etc., of light absorptive layers and to prevent the exposure of joint parts on a front surface by joining plural screen sheets at the cut faces inclined to the plane of the screen sheets within a non-effective part. CONSTITUTION:The joined screen sheet 20 is constituted by forming projecting parts 26 on the light exit side of non-light exit parts 22, coupling the valley parts C of the projecting parts 26 and the valley parts A of the lens elements 21 nearest the light incident side and joining the cut surfaces 25A, 25B inclined to the plane of the screen sheet with joining parts 27 consisting of adhesives, etc. The valley parts C of the projecting parts 26 are the ends of junctures 27. The plural screen sheets to be joined are joined by shifting one 20A of the plural screen sheets to the light exit side from the other 2OB, thereby, the screen sheets are joined in the state of maintaining the pitch of the lenticular lenses even if the adhesive layers are interposed in the joining parts 27.
