Patent ID: 8072551

Claim:
A projector comprising: a plurality of light modulation elements adapted to modulate a plurality of colored light beams with respective color components based on image data; a combining optical system adapted to combine the colored light beams, which are modulated by the respective light modulation elements, to emit the combined colored light beams as image light; and a projection optical system adapted to project the image light emitted from the combining optical system on a projection screen, wherein, the light modulation elements are disposed with respect to the combining optical system so that long sides of the respective light modulation elements are adjacent to each other, signal line cable boards adapted to provide the respective light modulation elements with signals, and coupled to short sides of the respective light modulation elements, and a scanning direction of writing the image data to the light modulation elements is set to be parallel to a direction of the short side of an image display area in each of the light modulation elements.
