ABSTRACT:
To provide an optical device by which the ease of assembly, and image quality and cooling performance an optical device includes light modulators and a light combining device to combine optical images includes fixing members opposing located to the luminous flux incident end surfaces of the light combining device and fixed to the light combining device and holding members provided to the fixing members to hold the light modulators. The fixing members and the holding members are formed to have C-shaped sections having base portions formed of rectangular plates in which opening portions to transmit luminous fluxes and pairs of standing pieces standing from the outer peripheral edges of the base portions and are opposed to each other. The pairs of standing pieces of the fixing members and the pairs of standing pieces of the holding members are slidingly fit together.
