Abstract: A substrate is pulled to a stretch ratio, and a liquid crystal material is then spread on a surface of the substrate to form a liquid crystal layer. Next, a protection layer is adhered onto the liquid crystal layer, thus forming an optical compensation film. The manufacturing of the optical compensation film uses substrate extension to replace a conventional alignment layer technique; the manufacturing efficiency and yield are therefore raised, and the manufacturing cost is reduced. Moreover, the arrangement uniformity of liquid crystal molecules is substantially improved, thus effectively enhancing the compensation and optical performance thereof.

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.
