Patent ID: 7715096

Claim:
A light diffusing screen for a transmission projection screen, which is a light diffusing screen for a single light source-type rear projection television, adapted for use in combination with a Fresnel lens sheet, said light diffusing screen comprising: a lens layer which can horizontally refract projected light; and a light diffusing layer provided on light outgoing side as compared with said lens layer, said light diffusing layer comprising a light transparent matrix and light diffusing fine particles formed of a light transparent material dispersed in the light transparent matrix, said light diffusing layer having a multilayer structure of which the outermost layer on the light outgoing side of said light diffusing layer is a layer which diffuses light most strongly, said outermost surface layer on the light outgoing side in said light diffusing screen having a surface roughness Ra of 0.2 μm≦Ra≦1.0 μm.
