Abstract
A stereo display device uses a display unit having a pair of substrates each being formed with a pattern of electrodes and a material filled in a space between the substrates. The material has an electrically controllable optical characteristic for effectuating a display when a voltage is selectively applied to the electrodes on the respective substrates. One of the substrates confronting the viewer is a transparent substrate. The stereo display device also uses a plurality of optical elements formed on a transparent substrate for refracting rays of light incident thereupon, thereby causing travel in different directions as determined by the position at which the rays of light have impinged upon the optical elements. Two image display electrode elements, one associated with the left-hand eye and one with the right-hand eye of the viewer, are formed on the transparent substrate for each optical element.
