Claim Text:
1. An image display apparatus characterized by comprising: a light source for emitting out parallel light, a light deflector capable of deflecting the parallel light emitted out from said light source, a control unit operable to produce a scan signal for deflecting said light deflector periodically, and produce a light intensity control signal in sync with said scan signal based on entered image information thereby controlling said light source, and a light guide for guiding parallel light emitted out from said light source into said light deflector, wherein said light guide comprises two mutually opposed surfaces, said two surfaces being reflecting surfaces that alternately reflect parallel light emitted out of said light source plural times for propagation of said parallel light between them, wherein either one of said two surfaces forming said light guide is an exit surface from which a part of said parallel light exits toward a direction in which said light deflector is located, and wherein said two surfaces are each a transmitting surface for transmitting light deflected by said light deflector.
