Abstract
The present invention includes a reflection portion which light-modulates three primary color lights by three rectangular reflective liquid crystal light modulators, then color-combine the light-modulated lights and reflects the resultant light; and a projection lens which projects the reflected color-combined light onto a plane mirror. The three reflective light modulators are arranged in such a manner that their long side directions coincide with a perpendicular direction, and two of the three reflective light modulators are arranged in such a manner that their short side directions become parallel with a projecting direction of image light from a color separation/combination optical system.
