Abstract:
A screen allows an image according to light incident in an oblique direction from a predetermined light exiting position to be displayed. The screen includes a screen body having a reflection surface with a plurality of lens elements formed thereon, each of the lens elements reflecting the light incident thereon, a first layer (substrate) disposed on the side of the reflection surface on which the light is incident, and a second layer (air layer) interposed between the screen body and the first layer. The first layer has a refractive index greater than the refractive index of the second layer. The first layer has an angle changing portion formed in at least part of a region through which the light incident thereon passes, the angle changing portion so formed that the thickness thereof continuously increases with distance from the light exiting position.
