Patent ID: 7168811

Claim:
A projector, comprising: a light source to emit illumination light; a color separation optical system to split the illumination light into illumination light with at least two colors; a plurality of display elements including a plurality of pixels to modulate the illumination light; a color synthesizing optical system to synthesize image light formed by the plurality of display elements; a projecting device to project the image light synthesized by the color synthesizing optical system; an irradiation optical system to irradiate the illumination light emitted from the light source onto some of the pixels; and an illumination light scanning device to scan the illumination light irradiated by the irradiation optical system, each of the display elements being disposed to correspond to a single color, the irradiation optical system including an image forming device to condense the illumination light emitted by the light source to form an image and an image re-forming device to form the image formed by the image forming device on the display elements, and the illumination light irradiated onto the display elements being irradiated onto the display elements by at least the image forming device and the image re-forming device.
