ABSTRACT:
A stereoscopic image display apparatus including a liquid crystal display of light transmission type for displaying right-eye and left-eye target images, a pair of CRTs for displaying illuminating graphic patterns for illuminating the display from the back surface, and a Fresnel lens 11 arranged before the CRTs to show the viewer given displayed portions on the display screens of these CRTs in an enlarged scale. A first graphic pattern polarized in the X direction is displayed at a first position, which corresponds to the right eye of the viewer, on the display screen of the first CRT. A second graphic pattern polarized in the Y direction perpendicular to the X direction is displayed at a second position, which corresponds to the left eye of the viewer, on the second CRT. The display screen of the liquid crystal display is illuminated from the behind by the light from the first and second graphic patterns displayed on the CRTs, respectively. The liquid crystal display displays the right-eye target image and the left-eye target image such that the polarizing directions of the right- and left-eye target images agree with the polarizing directions of the first and second graphic patterns, respectively.
