ABSTRACT:
A projector to be simple and capable of being miniaturized. White light is decomposed by a color decomposition/composition device into red light, green light, and blue light, which are incident to a first, second, and third mirror deflection type light modulators and first effective reflected light to third effective reflected light obtained by the first, second, and third mirror deflection type light modulators are composed together, so that color decomposition/composition can be performed by the color decomposition/composition device eliminating the necessity of separately provided color decomposition and composition optical systems, and consequently it is possible to construct the optical system with ease, thereby realizing a projector which is simple and can be miniaturized.
