Patent ID: 8192029

Claim:
An image display device comprising: a laser light source having an emitting array including a plurality of emitting sections arrayed in a predetermined direction; a light modulation device that is a liquid crystal element, has an illumination region in which a plurality of light modulation pixels are two-dimensionally arrayed and modulates laser lights emitted from the laser light source in accordance with an image signal, the illumination region extending in a longitudinal direction and in a lateral direction; an optical element converting the laser lights emitted from the laser light source, into a linear laser light; and a scanning section scanning the linear laser light emitted from the optical element onto the light modulation device, wherein the predetermined direction in which the emitting sections are arrayed coincides with the longitudinal direction of the illumination region of the light modulation device, and wherein the light modulation device writes or overwrites pixel data by one pass scan method, and the scanning section scans the linear laser light so that the linear laser light is illuminated onto an area of the illumination region at which a transmissivity of the light modulation pixels has reached a predetermined value.
