Abstract
A display device can include a first display configured to produce an image and a plurality of transparent displays. Each of the plurality of transparent displays can be configured to produce a slice of the image to provide depth and a three-dimensional effect to the image, or at least one of the plurality of transparent displays can be configured to block, diffuse, or scatter light associated with the image produced by the first display so that different ones of a plurality of users see different content derived from the image produced by the first display. Each of the transparent displays can be substantially transparent. Further, at least one of the plurality of transparent displays can be made using Smectic A liquid crystals.
