    • PURPOSE: A lighting device is provided to inhibit the degradation of luminance at the intermediate area between linear-shaped light sources by respectively forming a prism portion and a lens unit on a first optical path change part and a second optical path change part. CONSTITUTION: A prism portion(61) of a first optical path change part(60) is arranged between a linear-shaped light source(30) and a diffusing plate(50). The prism portion is projected toward the linear-shaped light source. The first optical path change part varies the route of light from the linear-shaped light source and a reflecting plate(40). A second optical path change part(70) is arranged on the opposite side of the linear-shaped light source. A lens unit(71) is installed on the irradiating surface of the second optical path change part. The second optical path change part varies the route of the light passed the diffusing plate. The prism portion of the first optical path change part has the prism vertical angle of 55-75 degrees. The lens unit of the second optical path change part totally reflects some of the light towards the diffusing plate. The lens unit of the second optical path change part irradiates the light which passed the intermediate area of the linear-shaped light sources in the front direction.

    • An LCD(Liquid Crystal Display) is provided to have a polarization separating device, thereby returning the light of other wavelength band to a back light member. A back light member supplies the light. R filter(32R), G filter(32G), and B filter(32B) generate plural display light beams for displaying the color from the supplied light. An LCD panel(2) controls the polarizing direction of each display light so that the color display is performed. WGP(Wired Grid Polarizer)(33R,33G,33B)s are arrayed oppositely to each color filter, reflects the TE polarizing component of the light supplied from a back light member(4) and transmits the TM polarizing component. The WGP and a color filter(32) are stacked on the predetermined position of a base member(31). The base member is made of the light transmissive film such as polycarbonate or PET(Polyethyleneterephtalate), preferably, plastic materials.

    • PURPOSE: An anti-glare film is provided to prevent the color of a glare-proof film from being changed due to the diffused reflection of a lamp by regularly reflecting light entering in a shallow angle to a film plane. CONSTITUTION: An anti-glare film is composed of a transparent substrate(110) and an anti-glare layer(120) formed on the transparent substrate. The transparent substrate is composed of a transparent member of a sheet shape. The transparent substrate is made of a transparent resin including try acetylcellulose, polyethylene terephthalate, and acryl and polycarbonate. The anti-glare layer is made out of an ultraviolet hardening-type resin. The ultraviolet hardening-type resin is made of one or two or more kinds of multifunctional acrylate including TMPTA(Trimethylolpropane Triacrylat), PETA(Pentaerythritol Tetraacrylate), and DPHA(Die Pentaerythritol Hexaacrylate).
