    摘要: A 2-dimensional beam scan unit (2) reflects emission beams from a red laser light source (1a), a green laser light source (1b) and a blue laser light source (1c) and scans in a 2-dimensional direction. Diffusion plates (3a, 3b, 3c) diffuse the respective light beams scanned in the 2-dimensional direction to introduce them to corresponding spatial light modulation elements (5a, 5b, 5c). The respective spatial light modulation elements (5a, 5b, 5c) modulate the respective lights in accordance with video signals of the respective colors. A dichroic prism (6) multiplexes the lights of the three colors after the modulation and introduces the multiplexed lights to a projection lens (7) so that a color image is displayed on a screen (8). Since the 2-dimensional light emitted from the beam scan unit is diffused to illuminate the spatial light modulation element, it is possible to change the optical axis of the beam emerging from the light diffusion member for irradiating the spatial light modulation element moment by moment, thereby effectively suppressing speckle noise.
