Abstract:
1. An optical device, comprising: a plurality of optical modulators that modulate a plurality of color lights for each color light in accordance with image information; a color combining optical device having a plurality of light-incident sides facing the respective optical modulators, the color combining optical device combining the color lights modulated by the optical modulators, the color combining optical device being integrated with the optical modulators; an optical converting element provided between the optical modulator and the light-incident side, the optical converting element having a substrate on which an optical conversion film that converts optical characteristics of a light beam irradiated by the optical modulator, the optical modulator is connected through a heat-conductive material to an optical component casing accommodating optical components disposed on an optical path from a light source to the optical modulator, at least a part of the optical component casing being made of a heat-conductive material, and the optical modulator is attached to the color combining optical device through a position-adjusting spacer made of a heat-insulative material.
