    摘要: A projection screen using light control layers having high light diffusion and further providing an image with high image quality over a wide angle range without deteriorating light transmittance is provided. A plural number of light control layers in which a haze value of the layer is dependent on an angle and a light scattering angle region showing a haze value of 60% or more is in the range of 30° or more when light is injected on the surface of the layer at an angle of 0 to 180° are laminated to obtain a screen.
