A stereoscopic image display apparatus has a light source for emitting patterned light in a predetermined shape, an optical system having horizontal optical action and vertical optical action different from each other, and a display device. The display device displays a stripe image obtained by alternating stripe pixels from a parallax image for the right eye and stripe pixels from a parallax image for the left eye in a predetermined order. The patterned light is provided with directivity by the optical system to irradiate the stripe image. The light is separated into two areas, so as to permit an observer to visually recognize the stripe image as a stereoscopic image. In the stereoscopic image display apparatus, a difference DH between a horizontal pitch Hi of the patterned light and a horizontal pixel pitch Hd of the display device is not less than a predetermined value.
