摘要： A polarizer applied for a viewing side of a display is disclosed. The polarizer comprises a polarizing layer with an absorption axis, and a protective film disposed on the viewing side surface of the polarizing layer. The protective film includes a birefringent substrate adjacent to the polarizing layer having a birefringence difference not greater than 0.10 and having a slow axis and a fast axis perpendicular to each other, wherein the slow axis is parallel to the absorption axis of the polarizing layer, and an interference elimination layer disposed on a display side surface of the birefringent substrate, wherein the interference elimination layer has a diffusing layer disposed on the birefringent substrate, and a refractive-index-matching layer disposed on the diffusing layer, wherein with the total haze of the protective film is between 30% and 75% and the reflectivity of the protective film satisfies the relationship (RSCI-RSCE)≤1.0% and RSCE/(RSCI-RSCE)≥1.6, wherein RSCI is an average reflectivity of diffuse component and specular component (specular component included, SCI) of the protective film, and RSCE is an average reflectivity of diffuse component (specular component excluded, SCE) of the protective film.

摘要： The present invention is to provide an anti-glare film. The anti-glare film comprises a transparent substrate and an anti-glare layer formed on a surface of the substrate, wherein the anti-glare coating layer comprises 75 to 90 weight percent of an acrylic-based hard coating composition, 0.01 weight percent to 10 weight percent of silica nanoparticles and 5 weight percent to 20 weight percent of organic microparticles. The anti-glare film provides a satisfied anti-glare property and a surface fineness, and especially the anti-glare property at the wide viewing angle to enhance the visibility of the display.

摘要： A display is disclosed. The display comprises a display panel, and an optical film disposed on a viewing side of the display panel. The optical film has a total haze ranging from 15% to 60%, an inner haze less than or equal to 10%, and a reflectivity satisfying the relationships of 0.35%≤(RSCI-RSCE)≤1.50% and RSCE≤1.50%, wherein RSCI is an average reflectivity of diffuse component and specular component, and RSCE is an average reflectivity of diffuse component. By adjusting the total haze, inner haze and reflectivity of the optical film to satisfy the above relationship, the display can have good anti-glare properties, and the contrast ratio of the display will not be reduced too much to avoid the display quality be affected.

摘要： The present invention is to provide an anti-glare film. The anti-glare film comprises a polyethylene terephthalate (PET) substrate and an anti-glare layer formed on a surface of the PET substrate, wherein the anti-glare coating layer comprises 75 to 90 weight parts of an acrylic-based resin, 0.01 to 10 weight parts of silica nanoparticles 5 to 20 weight parts of organic microparticles and 0.05 to 2 weight parts of leveling agent. The anti-glare film has a total haze ranging between 35% and 50%, a surface haze ranging between 10% and 15% and a gloss at a viewing angle of 60 degrees between 30% and 50% thereof. The anti-glare film can provide satisfactory anti-glare properties, high precision, surface fineness, no flicker, good visibility and also fine adhesion between layers.
