Abstract
A rear projection television set is disclosed which includes a screen assembly, a reflector mirror located behind the screen assembly, and a projection source having a lens system for projecting rays of light to a rear side of the screen assembly through the reflector mirror. The projection source is arranged below the reflector mirror. A ray of light emitted along an optical axis of the lens system of the projection source is reflected by the reflector mirror. A positional relationship among the screen assembly, the projection source and the reflector mirror is determined so that the reflected ray of light is incidental from an upper side to a lower side relative to the screen.
