Claim:
An image display comprising: display means for displaying an image; a light source for applying light to said display means; first polarization axis control means for separating said light emitted from said light source into light having a first polarization axis and light having a second polarization axis in a state where at least a prescribed reference side of said display means is arranged in a first direction; and second polarization axis control means for separating said light emitted from said light source into light having at least two different polarization axes in a state where said prescribed reference side of said display means is arranged in a second direction intersecting with said first direction, for providing a stereoscopic image to an observer by progressing either said light having said first polarization axis or said light having said second polarization axis toward the eyes of said observer in said state where said prescribed reference side of said display means is arranged in said first direction, and providing said stereoscopic image to said observer by progressing light, having at least one said polarization axis, included in said light having at least two different polarization axes toward the eyes of said observer in said state where said prescribed reference side of said display means is arranged in said second direction.
