Abstract
An autostereoscopic display device comprises a display arrangement such as an emissive display arrangement or an reflective display arrangement, with an array of spaced pixels. A light guiding arrangement has an array of light guide columns, with one column over each display pixel or over a group (such as a column) of pixels. The light guide columns comprise aside wall which tapers outwardly to define a funnel shape with the pixel at the smaller base of the funnel. The funnel provides collimation to reduce cross talk in the display, which is particularly problematic for 3D autostereoscopic displays.
