Abstract:
A projector comprising:a light source; an electrooptic device that forms an optical image from light emitted from the light source in accordance with image information; a projection lens that enlarges and projects the image formed by the electrooptic device; an optical polarizing element interposed between the light source and the electrooptic device, a predetermined polarized light transmitted through the optical polarizing element being modulated by the electrooptic device; and a single adjustment mechanism that adjusts a mounting angle of an optical polarizing element, the adjustment mechanism comprising two frames, the optical polarizing element being supported by one of the two frames, one of the two frames being pivotally supported on a pivoting axis so that it can turn independently in relation to the other of the two frames, and an adjustment member that adjusts to pivot one of the two frames about the pivoting axis with respect to the other of the two frames, a direction of an axis of the adjustment member is aligned parallel to a tangential direction of a pivotal motion of the one of the two frames.
