Abstract:
A reflective screen includes a light reflecting layer, and a light diffusing layer provided on the light reflecting layer. The light diffusing layer has the diffusion property that in one (A axis) of two perpendicular axial directions on a light diffusion plane, a luminance distribution curve versus incidence angle is asymmetric with respect to the zero-incidence-angle axis, and the side on which the incidence angle (half-luminance incidence angle) with half of a peak luminance on the A axis in the normal direction to the screen plane is small faces in a direction in which external light has the highest strength.
