Abstract
Belt-like regions illuminated by red, green and blue light beams are formed on an image display panel, and the illuminated regions are moved continuously. Each pixel of the image display panel is driven by a signal corresponding to the color of light entering the pixel. This makes it possible to display a color image with only one image display panel having neither a color filter nor a pixel exclusively for the respective light beams. The adjacent regions illuminated by two colors of light are overlapped partially, and the pixels in the overlapping portions are driven by a brightness signal component. By overlapping the adjacent illuminated regions, a focused area of the light beams can be enlarged, achieving a smaller focusing optical system, making it possible to reduce the size of the entire device.
