A projector includes an illumination device adapted to emit a plurality of light beams, which includes a first light beam and a second light beam, as illumination light, a liquid crystal light valve, and a projection optical system adapted to project image light, which is emitted from the liquid crystal light valve, on a screen. The image light is formed of a plurality of diffracted light beams and a plurality of zero-order light beams, which are generated by the illumination light and the liquid crystal light valve. In the exit pupil, an illuminance peak due to the zero-order light beam corresponding to the first light beam is disposed at a position different from a position of an illuminance peak due to the diffracted light beam corresponding to the second light beam. |

1. A projector comprising:
an illumination device adapted to emit a plurality of light beams, which includes a first light beam and a second light beam, as illumination light; a light modulation device adapted to modulate the illumination light to thereby generate image light; and a projection optical system having an exit pupil and adapted to project the image light, which is emitted from the light modulation device, on a projection target surface, wherein the image light is formed of a plurality of diffracted light beams and a plurality of zero-order light beams, which are generated by the illumination light and the light modulation device, and in the exit pupil, an illuminance peak due to the zero-order light beam corresponding to the first light beam is disposed at a position different from a position of an illuminance peak due to the diffracted light beam corresponding to the second light beam. |
