    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： 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： A high-haze anti-glare film is disclosed. The high-haze anti-glare film comprises a transparent substrate and an anti-glare layer on the substrate. The anti-glare layer comprises acrylate binder, amorphous silica microparticles and spherical organic polymer microparticles, wherein the spherical organic polymer microparticles are monodispersity and the average particle size thereof is smaller than that of the amorphous silica microparticles. The total haze (Ht) of the anti-glare film is more than 40%, and the total haze is the sum of the surface haze (Hs) and the inner haze (Hi) of the anti-glare film, and the inner haze (Hi) and the total haze (Ht) satisfy the relation 0.25
