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 3):
The projection screen according to  claim 1 , wherein the projection screen has an overlapping internal structure in which the position of the upper end portion of the first internal structure and the position of the lower end portion of the second internal structure overlap each other in the film thickness direction.
