Patent ID: 7382539

Claim:
A projector comprising: an illuminating device having a light source device that emits an illuminating light beam on the side of an illuminated area; a first lens array having plural first small lenses that divides the illuminating light beam emitted from the light source device into plural partial light beams; a second lens array having plural second small lenses corresponding to the plural first small lenses; and a superposing lens that superposes the respective partial light beams emitted from the plural second small lenses in the illuminated area; an electro-optic modulator that modulates the illuminating light beam from the illuminating device; and a projection optical system that projects the illuminating light beam modulated by the electro-optic modulator; wherein a conjugate point of an image forming area in the electro-optic modulator being located on the light source device side or the projection optical system side from the vertex of a lens curved surface in each first small lens of the first lens array; and an eccentric amount of each second small lens in the second lens array being adjusted such that each principal ray of the partial light beam passing through each first small lens in the first lens array passes an approximately central portion of the image forming area on the image forming area of the electro-optic modulator.
