Abstract
An autostereoscopic display device has display elements, each of which has an output light intensity distribution which has at least two non-zero light intensity levels, comprising a first light intensity at the center of the display element area and a second lower light intensity at a periphery of the display element area. This means the light intensity drops more gradually at the pixel edges, so that the abrupt pixel edges are less visible despite the magnification provided by a lens arrangement of the autostereoscopic display device.
