Abstract: A multiview backlight and a multiview display employ a multibeam element configured to provide a tilted plurality of directional light beams having different principal angular directions corresponding to view directions of a plurality of view in a view zone. The multiview backlight includes a light guide configured to guide light as guided light and the multibeam element configured to couple out a portion of the guided light as the tilted plurality of directional light beams. A tilt angle of the tilted directional light beam plurality is provided by an offset of the multibeam element and a corresponding multiview pixel. The multiview display includes an array of multibeam elements and an array of multiview pixels.
