Abstract
A device for forming and displaying stereoscopic images is provided with a non-planar upper substrate having a series of alternating raised and depressed regions, a non-planar lower substrate having a shape corresponding to the upper substrate, the upper and lower substrates being arranged to form a plurality of shaped cavities therebetween. A light control material is provided within the shaped cavities and has a light transmissive property which is controllable in response to an electrical potential applied thereto. Control means are provided for controlling the light transmissive property of the light control material to selectively direct light from a light source through the light control material and upper substrate at predetermined viewing angles to thereby form and displace stereoscopic images.
