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. 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.
