Abstract
A stereoscopic image display method using a display, a phase shift member and a polarization optical element, two different types of vertically elongated stripe-shaped polarization plates having orthogonal optical axes, includes the steps of displaying, on the display, a single stripe image which is synthesized in such a manner that right and left parallax images from a parallax image source are divided into stripe pixels, and the stripe pixels of the right and left parallax images are arranged in a predetermined order, and controlling a direction of polarization of light transmitted through the phase shift member by controlling the electrical signal to be applied to the phase shift member in synchronism with the display operation of the stripe image.
