Abstract
A screen includes a plurality of reflecting portions disposed on a flat surface with a clearance left between one another. The reflecting portions reflect diagonal incident light coming in a predetermined direction other than the normal line direction of the flat surface, and block the diagonal incident light by reflecting the incident light such that the incident light cannot reach each area between the adjoining reflecting portions on the flat surface.
