Abstract
This invention relates to a stereoscopic image display apparatus, which comprises a two-dimensionally array of light modulation elements for modulating light in correspondence with a stripe synthesized image obtained by alternately arranging stripe image portions of a plurality of stripe images which are obtained by dividing right- and left-eye images, an illumination light source, arranged behind the light modulation elements, for illuminating the light modulation element, a parallax barrier arranged in front of the light modulation elements, and having predetermined aperture portions and light-shielding portions in correspondence with the light modulation elements corresponding to the respective stripe image portions, and an element, arranged between the light modulation elements and the illumination light source, for dividing and deflecting light emitted by the illumination light source.
