摘要： A projection type image display apparatus able to improve the utilization efficiency of light and attain a high luminance of light. An optical waveguide for guiding light emitted from a light source is provided, and a color separator for transmitting predetermined color light included in the light guided by the optical waveguide and for reflecting predetermined color light included in the guided light is also provided. The light reflected by the color separator is guided by the optical waveguide and is thereafter reflected by a reflecting member. The light reflected by the reflecting member is radiated into the optical waveguide and conducted thereby to the color separator.

摘要： An image display technique which projects R, G, and B light rays on a display device to form an image with an increased utilization ratio of light and an increased screen brightness. R, G, and B light rays as a result of color separation are reflected by plural reflective surfaces on the inner side, etc. of a rotary polyhedral reflector, so that, as the reflector rotates around a central axis and its reflection plane sequentially changes from one reflective surface to a next one, the reflected light rays are projected on a display device surface in different positions and scroll in a prescribed direction.
