A liquid crystal projector that has a plurality of light sources for providing light to a light crystal panel, which functions as an image forming unit in the projector. A plurality of light source driving power sources are connected to the plural light sources individually by means of a light source lighting control circuit. As the light source lighting control circuit, a delay circuit, a counter circuit, or a programmed microcomputer is used. By controlling the light source driving power sources, each one of the plural light sources lights up sequentially or alternately in time. The light emitted from the light sources is modulated by the liquid crystal panel to produce a light image, and the light image is projected through the projector lens.
