ABSTRACT:
A projector includes: a light source which emits light; an image forming unit which forms an image having desired size by using light emitted from the light source; and a projection unit which projects the image formed by the image forming unit on a light receiving surface. The projection unit has a light diffusing member disposed at a position where an intermediate image corresponding to light released from the image forming unit is formed to diffuse the light, and a projection system which projects the light diffused by the light diffusing member on the light receiving surface. Diffusion intensity distribution of light released from a predetermined position of the light diffusing member contains at least two prominences with the center axis of the light interposed between the prominences.
