Patent ID: 7137705

Claim:
An optical modulator, comprising: a plurality of optical modulators that respectively modulate a plurality of color lights in accordance with image information; a color-combining optical device that combines and irradiates the respective color lights modulated by the optical modulators; a plurality of fixing members that respectively fix the plurality of optical modulators relative to respective light-incident surfaces of the color-combining optical device; a base fixed on at least one of a pair of end surfaces crossing to the respective light-incident surfaces of the color-combining optical device; and a plurality of reinforcing members disposed on lateral end surfaces of the plurality of optical modulators in a facing manner, wherein supporting surfaces that support the plurality of reinforcing members are formed on the base, and wherein the plurality of reinforcing members are supported by the supporting surfaces, and also support and fix the respective lateral end surfaces of the plurality of optical modulators, so that fixing state of the plurality of optical modulators is enhanced relative to the respective light-incident surfaces of the color-combining optical device.
