ABSTRACT:
An image display apparatus includes: a light source; a first light modulation element which has a plurality of pixels whose light modulation characteristics can be independently controlled and modulates light emitted from the light source; a second light modulation element which has a plurality of pixels whose light modulation characteristics can be independently controlled and modulates light emitted from the first light modulation element; and a relay optical system disposed between the first light modulation element and the second light modulation element to create an image formation surface by forming an optical image produced by the first light modulation element at a predetermined position. A pixel surface of the second light modulation element is positioned away from the image formation surface of the optical image produced by the first light modulation element.
