Abstract
A display device includes a display panel having separately addressable pixels for displaying an image. A first pixel group of provides emergent light in a first polarization state, and a second pixel group provides emergent light in a second polarization state. A barrier layer in optical association with the display panel partially occludes the emergent light. The barrier layer has a first set of regions for passing light in one of the first or second polarization states, a second set regions for passing light in the other polarization state, and a third set of regions for occluding the emergent light. The first and second regions of the barrier layer are respectively registered with the first and second groups of pixels so as to provide different views of an image displayed by the display panel.
