Abstract:
A liquid crystal display comprising:a liquid crystal panel comprising front and back glass plates with a gap disposed therebetween, the gap accommodating a liquid crystal material between the front and back plates;a first polarizing plate having a surface facing a front side of said front glass plate of said liquid crystal panel, the surface of the first polarizing plate that faces the front side of the front glass plate being coated with an adhesive film, the front side of the front glass plate being coated with a transparent filler material;a directional backlight on a back side of said liquid crystal panel; anda light diffusing layer between the front side of said front glass plate of said liquid crystal panel and said first polarizing plate, wherein:said directional backlight generates incident light beams which are substantially perpendicular to said liquid crystal panel;said light diffusing layer for diffusing said incident illumination light beams leaving said liquid crystal panel and comprises transparent fine particles spread over the adhesive film of the first polarizing plate so that said transparent fine particles are disposed in a space between the front glass plate of said liquid crystal panel and said first polarizing plate, said light diffusing layer further comprising transparent filler material filling up gaps among said transparent fine particles;said first polarizing plate being adhered to said front glass plate of said liquid crystal panel by said adhesive film and transparent filler material;said transparent fine particles each have a refraction index different from that of said front and back glass plates; andsaid transparent filler material has a refraction index substantially the same as that of said front glass plate wherein the liquid crystal panel is a flat panel and wherein the refraction index of the transparent fine particles is larger than that of the transparent filler material and the transparent filler material is comprised of a degenerated acrylate, the transparent filler material having a viscosity of about 20 cp.
