Abstract:
1. An image display device, comprising: a first color-ray light-source that supplies a first color-ray in a first wavelength region; a second color-ray light-source that supplies a second color-ray in a second wavelength region different from the first wavelength region; a tilt-mirror device having a plurality of movable mirror elements having positions thereof alternatively switchable between a first reflection position and a second reflection position, the first color-ray light-source being arranged so that the first color-ray is reflected in a predetermined direction when the movable mirror elements are located in the first reflection position, and the first color-ray is reflected in a direction different from the predetermined direction when the movable mirror elements are located in the second reflection position, the second color-ray light-source being arranged so that the second color-ray is reflected in the predetermined direction when the movable mirror elements are located in the second reflection position, and the second color-ray is reflected in a direction different from the predetermined direction when the movable mirror elements are located in the first reflection position, and the movable mirror elements being rotatable around a predetermined shaft; and a tilt-mirror device driving unit that drives that movable mirror elements corresponding to an image signal, so as to be switched at the first reflection position and the second reflection position, which is substantially symmetrical with the first reflection position around the predetermined shaft.
