Abstract
A stereoscopic image display apparatus for stereoscopically viewing an image displayed on a display, by transmitting light through a mask pattern where plural apertures and plural light shielding portions are arranged in a predetermined pitch in the horizontal and vertical directions, transmitting the luminous flux through an optical system for illuminating the display where at least two parallax images are displayed, and leading the luminous flux based on the two parallax images displayed on the display to the right eye and left eye of a viewer respectively. The apparatus enables to give flexibility to precise adjustment during the assembly and enables the viewing of a stereoscopic image from a wide area with good quality, by setting vertical widths Vt and Vs of the aperture and the light shielding portion of the mask pattern, and horizontal widths Ht and Hs of the aperture and the light shielding portion of the mask pattern to satisfy the relationship of Vt<Vs and Ht<Hs.
