Abstract
A stereoscopic image display apparatus comprising a light source for emitting light from plural apertures, an optical element array composed of an array of optical elements having different optical functions in the horizontal and vertical directions, for giving directivity to the light emerging from the apertures, and a transmissive display device for displaying a stripe image, obtained by dividing each of a parallax image for the right eye and a parallax image for the left eye in the vertical direction to obtain right stripe pixels and left stripe pixels and arranging the right and left stripe pixels alternately in a predetermined order, wherein the plural apertures are provided corresponding to each of the optical elements constituting the optical element array, for each stripe pixel, and are adapted to cause the light, passing through the right or left stripe pixel, to reach a predetermined area.
