Abstract:
A projector, comprising:a lighting device having a plurality of lamp units, each the lamp unit including a light source lamp and a reflector that reflects light emitted from the light source lamp; a color separation device that separates light emitted from the lighting device into at least two color light fluxes; and a plurality of modulation devices that modulate the respective color light fluxes separated by the color separation device, the projector further comprising: a color combining device that combines the color light fluxes modulated by the plurality of modulation devices; and a projection optical system that projects a composite light flux obtained by the color combining device onto a projection plane, wherein when x, y, and z denote three directional axes perpendicular to one another and z represents a direction parallel to an optical axis of light emitted from the lamp unit, the color separation device has a color separation plane that is substantially perpendicular to an x-z plane and has predetermined angles with respect to a y-z plane and an x-y plane, and the plurality of lamp units are arrayed substantially along the y direction.
