Abstract
A translucent projector screen on which light from a display unit disposed obliquely forward of the screen is projected, said projector screen integrally includes: a sheet-shaped main body; a plurality of convex lenses integrally formed on a surface of the main body; and a plurality of reflective members disposed on the main body corresponding to the convex lenses and respectively reflecting the display light emitted to the convex lenses in a specific incident angle toward the convex lenses other than the convex lenses to which the display light is emitted. The convex lenses have spherical surfaces or aspheric surfaces so that respectively collect the display light to the reflective members, and emit the display light reflected by the reflective members in a specific output angle.
