Abstract:
1. A projector, comprising: a color separation system that causes illumination lights of first through third colors to branch from a light-source light emitted from a light source and guide the illumination lights of the first through third colors to first through third optical paths, respectively; first through third light modulation devices to be illuminated, respectively, by the illumination lights of the first through third colors and independently modulate the illumination lights of their respective colors; a distance from the light source to the third light modulation device being different from a distance from the light source to the first light modulation device and a distance from the light source to the second light modulation device; a relay system that is disposed in each of the first and second optical paths or in the third optical path alone; and a correcting system that corrects a chromatic aberration that affect sizes of illumination areas, for at least the first color and the second color, by adjusting an angle distribution of the illumination lights of the first through third colors that are incident on the first through third light modulation devices, the correcting system being disposed prior to the first through third light modulation devices in the first through third optical paths.
