ABSTRACT:
To provide a display device and a projector capable of enhancing the quality of dynamic images, of reducing limitations on light sources, enhancing the utilization efficiency of light, and of displaying images in full color, illumination light emitted from a light source lamp is irradiated onto some pixels of a liquid crystal light valve capable of displaying images in colors. A rotating prism scans the illumination light. At this time, fly eye lenses and an superposing lens condense illumination light emitted from the light source lamp to form an image. The image formed by the fly eye lenses and the superposing lens is formed again on the liquid crystal light valve by the image re-forming lenses. The image of the liquid crystal light valve is enlarged and projected by the projection lens to a screen.
