Abstract:
A projector includes: a light source having a plurality of light emitting sections; a light modulation device including a reflecting section adapted to reflect the light from the light source in accordance with image information; and a projection lens adapted to project an image formed by the light modulation device, wherein the light from the light source obliquely enters the reflecting section, the light source includes a first region where the light emitting sections are disposed at a first density, and a second region where the light emitting sections are disposed at a second density higher than the first density, and a distance between the first region and the reflecting section is shorter than a distance between the second region and the reflecting section.
