Abstract:
An image display device for displaying images on a screen, comprising:a columnar display unit, comprising a plurality of means, arranged in parallel, which emit one-dimensional images; a control member which applies image signals to said columnar display unit; a perpendicular deflection means, which deflects light emitted from said columnar display unit in directions perpendicular to the column direction, and scans said screen; an image-forming optical system which forms an image, from said perpendicular deflection means, on said screen, according to the change in the distance from said columnar display unit to said screen; a light source, comprising a plurality of color components, and which irradiates said columnar display unit; a color separation means which separates light emitted from said light source into each color component, for incidence on each respective columnar display subunit corresponding to each color component; and optical combination means which combines light, of a plurality of colors and passed through the columnar display subunit corresponding to each color component, such that there are no shifts in position of each color component, for incidence on said perpendicular deflection means; wherein said columnar display unit modulates irradiated light, and wherein said columnar display unit modulates irradiated light, and wherein said plurality of means, which emits one-dimensional images, is a transmissive liquid crystal display element.
