PROBLEM TO BE SOLVED: To provide a liquid crystal projector capable of preventing the contrast of a video from being lowered in the adjustment of white balance. SOLUTION: In this liquid crystal projector 11, illuminating light from a light source is spectrally split to red, green and blue primary-color light beams, the illuminance of the red, green and blue primary-color light beams is adjusted by illuminance adjusting means for red, green and blue 12R, 12G and 12B, and the red, green and blue primary-color light beams are transmitted through liquid crystal displays for red, green and blue 13R, 13G and 13B, then they are synthesized by a synthesis prism 14 to be projected by a projection lens 16 attached to a housing 15.
