    摘要: A projection image display device includes, a light source, an image display panel having a number of pixels and a vertical scanning function, an optical system for dividing light from the light source into a plurality of lights of different wave ranges and directing and overlapping the divided plural lights onto an area from different directions, a light-collector for collecting each of the plural divided lights directed onto the area by the optical system into apertures of pixels of the image display panel corresponding to the wave range of the light, a projector for projecting an image displayed on the image display panel, and a color-changer for mutually changing, at every vertical scanning of the image display panel, the directions in which the optical system directs the plural divided lights of the different wave ranges, so as to mutually change the wave ranges of light directed to the pixels of the image display panel sequentially. The image display panel displays an image with each of the pixels displaying a color of the wave range of light directed to the pixel at every change by the color-changer.
