Abstract:
Provided is a projection screen which can effectively diffuse incident light coming from a wide angle, despite that the number of laminated sheets of a light diffusion control film is small such as 3 to 4 sheets, and can thereby provide a wide viewing angle even if the projection screen is applied to a large-sized screen. Disclosed is a projection screen having a light diffusion control plate, the light diffusion control plate being formed by laminating a plurality of sheets of a light diffusion control film, the light diffusion control film being a light diffusion control film having a single light diffusion layer having a first internal structure and a second internal structure sequentially from the lower part along the film thickness direction, in which the first internal structure is a predetermined louver structure, and the second internal structure is a predetermined columnar structure.

Claim (Index 1):
A projection screen comprising a light diffusion control plate,\n the light diffusion control plate being formed by laminating a plurality of sheets of a light diffusion control film, the light diffusion control film being a light diffusion control film having a single light diffusion layer having a first internal structure for anisotropically diffusing incident light and a second internal structure for isotropically diffusing incident light sequentially from the lower part along the film thickness direction, wherein the first internal structure is a louver structure formed by alternately arranging a plurality of plate-shaped regions having different refractive indices in any one direction along the film plane, and the second internal structure is a columnar structure formed by arranging a plurality of pillar-shaped objects having a relatively high refractive index to stand close together in the film thickness direction in a region having a relatively low refractive index.
