Abstract: PURPOSE:To improve both a color reproducibility and a light utilizing efficiency by specifying the three primary colors of both the light energy with which a liquid crystal light valve is irradiated and a brightness made incident on a projection lens. CONSTITUTION:Light are made incident from a light source 1 to a liquid crystal light valve 8, and an image on the liquid crystal valve 8 is connected with a place parted only by a prescribed distance after allowing the light to pass a projection lens 9. Then, the light energy with which the liquid crystal light valve 8 is irradiated, and the brightness made incident on the projection lens 9 are constituted so that the three primary colors R : G : B can be equal to 3 : 6 : 1. Therefore, the light energy of the light in a wavelength area in which the light sensitivity of a semiconductor layer which drives the liquid crystal light valve 8 is strong, that is a blue color area, is weak, so that the change of the liquid crystal light valve 8 with time which is irradiated with the light in the blue color area can be suppressed. Thus, the unbalance of a color purity can be prevented, and the liquid crystal light valve 8 can be driven in a full range.
