Abstract
An optical device includes a plurality of light modulators that modulate a plurality of color light components according to image information about each color light component and a combining optical unit that combines modulated color light components involving corresponding images for color light components irradiated out of the light modulators and irradiates combined-modulated light components outside through the irradiating surface. The light modulators face each other through incident surfaces which the modulated color light components pass through, other than the irradiating surface of the combining optical unit having an upside and bottom and a plurality of sides, and parts of the light modulators are supported by supporting substrates of a plate that are mounted at the upside and bottom.
