The length of the optical path of each color light beam, that is, the distance from the light source lamp 181 to each liquid crystal panel, is the longest for the blue light beam B, and therefore, the light amount loss of this light beam is the largest. However, by interposing the light guide system 927, the light amount loss can be suppressed.

Next, each liquid crystal light valve 925R, 92
R, G, and B light beams modulated through 5G and 925B, respectively.
Are incident on the prism unit 910 through the exit-side polarizing plates 961R, 961G, and 961B, and are synthesized there. The color image synthesized by the prism unit 910 is enlarged and projected on the projection surface 100 at a predetermined position via the projection lens 6.
