Beschreibung
Zusammenfassung:	A display device includes an image projection device, a light guide plate, and a mask. The light guide plate includes deflectors arranged in a propagation direction of a light beam emitted from the image projection device and entering the light guide plate. Each deflector causes light beams to be emitted from an outgoing surface at angles different from each other in the propagation direction, the light beams emitted from locations different from each other or emitted in directions different from each other in a direction orthogonal to the longer direction of an incident surface in a displayed region of the image projection device. The mask shuts-off light beams other than a light beam directed toward a predetermined viewpoint among light beams emitted from the outgoing surface. The image projection device collimates light beams emitted from the region, in the direction orthogonal to the longer direction of the incident surface.
