A first portion of the polarizer is adjacent to a backlight source and has a first protective film, a first linear polarizing film, a first biaxial film and a first quarter-wave film from the backlight source to a multi-domain vertical alignment liquid crystal (MVA-LCD) cell. A second portion of the polarizer is on the other side of the MVA-LCD cell, and has a second quarter-wave film, a second biaxial film, a second linear polarizing film and a second protective film from the MVA-LCD cell.

Abstract: A plasma display panel structure having polarization plate is comprised of plasma display panel and filter, wherein the plasma display panel includes front glass and rear glass. Through the front glass, the plasma display panel displays images to the outside. The location of rear glass is corresponding to that of front glass and there is plasma enclosed between the rear glass and the front glass. The filter is a multiple-layer structure having polarization plate and is disposed upon the front glass. In this plasma display panel structure including plasma display panel having polarization plate, since the polarization plate is comprised in filter, so the showed picture is more color-contrasted and more three-dimensioned after the images showed by the plasma display panel passes through this filter.

Abstract: A structure of light control membrane is mainly comprised of a single layer of light-conducting membrane as a substrate, wherein the surface of the light-conducting membrane particularly has an opaque zone in spiral shape or multi-layer circular rippling wave shape. When a user views an image through the light-conducting membrane, the opaque zone in spiral shape or multi-layer circular rippling wave shape will make the image visible only within a specific range of viewing angle while, out of the specific range of viewing angle, the image is invisible.

Abstract: A polarizer to improve contrast for LCD from down view angle is produced by laminating a triacetate cellulose (TAC) sheet on each side of a polyvinyl alcohol (PVA) sheet and further on the toppest triacetate cellulose (TAC) sheet applying a surface-treatment layer that is a protective film formed by black dye mixture to inhibit dark-state light leakage and improve the contrast for LCD from down view angle.

Abstract: A transparent resin having a plurality of transparent particles is spread on an optical sheet. The transparent resin is exposed to ultraviolet light of a first power and then cured by ultraviolet light of a second power, which is greater than the first power. Thus, surface optical layers with different optical properties are easily obtained by only adjusting the power of ultraviolet light, without changing the original content of the surface optical layer or the parameters of its spreading process.

Abstract: An antiglare film applicable to polarizers or displays includes a light-transparent resin, first light-transparent particles dispersed on surface of the light-transparent resin and second light-transparent particles dispersed inside the resin. The first light-transparent particles have a same refractive index as that of the resin and particle diameters of 9 to 500 nanometers that provide a less roughness surface of the resin in order to prevent from large angle diffusion to the interior light and improve clarity of image. The second particles have a different refractive index from the resin so as to diffuse the exterior light that comes to the antiglare film so as to decrease glare. The antiglare film can be made by one time of coating. The two layer light-transparent particles provide light interference and achieve a low reflectivity.
