Zusammenfassung:	A display device including a light source and a wedge lightguide defining a light-inlet side, a display side, and a back side, the display and back sides facing in different directions and forming a wedge-shape that defines a convergence axis, the light-inlet side positioned at a divergent side of the wedge-shape and the back side facing away from a display surface of the display device. The back side includes a plurality of wedge extractors, each wedge extractor extending in a direction substantially orthogonal to the convergence axis. The light source positioned adjacent to the light-inlet side of the wedge lightguide. The wedge lightguide is configured to receive light rays from the light source through the light-inlet side and transmit the light rays through the display side an exit angle with a maximum intensity at between about 10° and about 40° measured from a plane defined by the display side.
