A projector includes an illumination device including a light source that outputs light from a light emitting part, a first lens array having plural first small lenses, a second lens array having plural second small lenses corresponding to the plural first small lenses, and a superimposing lens that superimposes lights from the second lens array, a light modulation device that modulates light from the illumination device in response to image information, and a projection optical system that projects the light from the light modulation device on a projection target, wherein radii of curvature of the first small lenses are set with respect to each first small lens. |
