ABSTRACT:
A light diffusion composite comprises a light diffusion material disposed on a prism sheet, wherein the light diffusion material is obtained by laminating a light diffusion layer including 100 parts by weight of acrylic resin and 100-220 parts by weight of spherical particles of polymethyl methacrylate on a transparent support. The light diffusion composite has better luminance in the front direction than the conventional light diffusion sheet and also has good light diffusibility.
