Patent ID: 7180676

Claim:
A projector, comprising: a light source device; an optical modulator arranged on an illumination optical axis of a light beam irradiated by the light source device to modulate the light beam in accordance with image information and form an optical image; a projection lens that enlarges the optical image formed by the optical modulator and projects the optical image; and an optical converter arranged between the optical modulator and the projection lens and provided with an optical conversion area that optically converts the incident light beam, wherein the optical conversion area of the optical converter is formed in a profile on which substantially all of the light beams irradiated from the optical modulator to be irradiated from the projection lens as the optical image are incident, the optical modulator has a center axis passing through the center of an optical image formation area of the optical modulator and being parallel to the illumination optical axis, the projection lens is so arranged that a lens optical axis of the projection lens is deviated in parallel relative to the center axis of the optical modulator, and the center axis passing through the center of the optical conversion area and being parallel to the illumination optical axis is positioned within a range between: a plane orthogonal to a deviation direction of the lens optical axis of the projection lens relative to the center axis of the optical modulator and including the center axis of the optical modulator; and a plane orthogonal to the deviation direction and including the lens optical axis.
