摘要： A projector includes: an illumination device; first color separation device that separates first and second color light from light emitted from the illumination device; second color separation device that separates third and fourth color light from the second color light; plurality of light modulation devices that modulate the lights separated by the first and second devices; projection optical device that projects an image based on the modulated lights; first and second filters provided on optical paths of the third and fourth color lights, respectively. A wavelength of the third color light is shorter than that of the fourth. The first filter attenuates light at a wavelength exceeding a first threshold set in a dimming wavelength region between a wavelength region of the third and fourth color lights. The second filter attenuates light at a wavelength equal to or less than a second threshold set in the dimming wavelength region.
