Abstract:
A projector includes a light source device which emits an illumination light; an aperture disposed with a tilt with respect to a plane perpendicular to a center axis of the illumination light, provided with an opening section which transmits a part of the illumination light, and block a rest of the illumination light; a pair of first and second lens arrays which divides the illumination light from the light source device into a plurality of partial light; and an overlapping lens which overlaps the illumination light transmitted through the first and second lens arrays, wherein the aperture is disposed on a light path between the light source device and the overlapping lens.
