PURPOSE: To provide the screen having high brightness and high contrast by laminating a transparent light diffusion layer on a reflection sheet arranging many fine convex mirrors on a projecting light side.

CONSTITUTION: The reflection sheet 1 may be a sheet formed by kneading glitters into a transparent plastic sheet itself and forming fine projections on its surface to form convex mirrors 5 or a sheet formed by coating the surface of a plastic sheet previously forming fine projections on it with a light reflection layer 11 to form the convex mirrors 5. The reflection layer 11 is formable by coating with a glitter pigment or a metal. The shape of the fine projections constituting the convex reflection mirrors 5 includes a so-called flyeye lens shape or lenticular lens shape. The transparent light diffusion layer 3 is formed by coating with a coating material contg. a light diffusion material or lamination of a transparent resin layer into which the light diffusion material is dispersed and incorporated. As a result, the higher brightness images are obtd. by the smaller light quantity for projection and the contrast is distinct.
