Abstract
Aspects of the invention can provide an image display device for modulating light from a light source on the basis of display image data to display an image. The image display device can include a first optically modulating device for modulating light from the light source, a second optically modulating device for modulating light from the first optically modulating device, a relay lens system provided between the first optically modulating device and the second optically modulating device for forming an optical image of the first optically modulating device on a light-receiving surface of the second optically modulating device, and at least one reflecting optical device provided between plural lenses forming the relay lens system.
