Abstract
According to one embodiment, a display device includes a display, an optical unit, and a reflector. The display includes a first display region emitting a first bundle of rays and a second display region emitting a second bundle of rays. The optical unit includes first and second emission regions transmitting the first and the second bundle of rays. The reflector includes a first reflection region reflecting the first bundle of rays, and a second reflection region reflecting the second bundle of rays. The optical unit forms a first focal point of the first bundle of rays between the optical unit and the reflector, and forms a second focal point of the second bundle of rays between the optical unit and the reflector. A distance between the first emission region and the first reflection region is shorter than a distance between the second emission region and the second reflection region.
