ABSTRACT:
A screen includes a front surface structure section including a lens array having a plurality of element lenses arranged on a two-dimensional plane on a front side of the screen, a rear surface structure section including a plurality of scattering surfaces formed on a rear side of the lens array so as to be tilted with respect to the two-dimensional plane, and adapted to emit projection light, which has been input, towards the front side of the screen while scattering the projection light, and an adhesive layer adapted to bond the front surface structure section and the rear surface structure section to each other, and the rear surface structure section is composed mainly of a plurality of rear surface forming sections different from each other in a pattern of the plurality of scattering surfaces.
