Claim:
A projector, comprising: 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, wherein 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, and from the light diffusing member to the light receiving surface, there is a difference in an optical path length between a light beam on one side of a center axis of light and a light beam on an other side of the center axis of light.
