Abstract:
A stereoscopic image display apparatus comprising;light providing means for providing patterned luminous flux including plural light existing areas and plural light non-existing areas each of which are arranged both in the horizontal and vertical directions;optical means having an array of optical elements each having a lens function at least in the vertical direction;a display device for displaying two parallax images for respective one of right and left eyes of a viewer by being illuminated with the patterned luminous flux via said optical means, for leading the luminous flux from the parallax image for the right eye to the right eye and for leading the luminous flux from the parallax image for the left eye to the left eye, thereby enabling stereoscopic viewing of a image;wherein assuming vertical widths of the light existing areas and light non-existing areas are Vt and Vs respectively, the vertical widths are set so as to satisfy the relation of Vt<Vs.
