Abstract:
A projector comprising:a plurality of optical modulation devices for modulating a plurality of colored light beams in accordance with image data; a prism for combining the light beams modulated by the optical modulation devices, the plurality of optical modulation devices being mounted on the prism at side faces thereof at a predetermined distance from the side faces of the prism; a projection lens for enlarging and projecting the light beams combined by the prism; and a light shielding member that shields light which leaks from gaps between the optical modulation devices and the side faces of the prism toward the projection lens side, the light shielding member providing an opening that leads therethrough light beams emitted from the prism and a positioning part that determines the relative position between the opening and a light emission surface of the prism, the opening being formed in a shielding part disposed in contact with the light emission surface of the prism, the shielding part is fixed to the light emission surface of the prism, and the positioning part is fixed to a surface of the prism other than the light emission surface thereof.
