Claim:
An image display apparatus comprising: an image display device including pixels to display a right-eye image and a left-eye image for displaying a three-dimensional image, the pixels including pixel pairs that have pixels arranged to be adjacent across first light-shielding portions, the pixel pairs being arrayed across second light-shielding portions; a first optical shutter device that is placed on a rear side of the image display device, which is opposite to a viewing side thereof, and includes first light-transmitting portions that are placed at positions corresponding to the first light-shielding portions of the image display device, transmit light toward the pixel pairs of the image display device, and cause image light beams passing through the pixels of the pixel pairs to strike a right eye and a left eye of a viewer located in a predetermined first viewing direction, and first shutter portions to control transmission/shielding of light with respect to an area other than the first light-transmitting portions; and a second optical shutter device that is placed on a front side of the viewing side of the image display device, and includes second light-transmitting portions that are placed at positions corresponding to the second light-shielding portions of the image display device, and cause image light beams respectively passing through the pixels of the pixel pairs that are adjacent to each other across the second light-shielding portions to strike right eyes and left eyes of viewers located in a predetermined second viewing direction and a third viewing direction different from the second viewing direction, and second shutter portions to control transmission/shielding of light with respect to an area other than the second light-transmitting portions.
