To provide a screen free from the lowering of a contrast by arranging a diffusion layer only on a light transmission part under the light convergence, and having an improved vertical viewing angle by eliminating a hot bar.
As for the screen, a base material layer 11 formed of plastic resin is arranged on the flat surface side of a lens surface forming layer 12 which is constituted of a cylindrical lens surface with semicolumnar convex lenses arranged side by side and the flat surface, and a black stripe 14 is arranged on the side not coming into contact with the lens surface forming layer of the base material layer. In this case, milky pigment is mixed in the plastic resin, the milky pigment has diffusion work and prevents ultraviolet light to be diffused even in the case the light is condensed.
