Projection screen

A projection screen comprising 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 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,
• wherein a plurality of the sheets of the light diffusion control film are composed of first to third light diffusion control films having the same configuration, and the first to third light diffusion control films are laminated such that the directions of exit of the first to third light diffusion control films are respectively in different directions.
