Title: DISPLAY DEVICE, DISPLAY SYSTEM, AND MOBILE BODY
Abstract:
This display device (30) comprises a display element (32), an optical element (33), a projection optical system (20), a driver (36), and a controller (35). The display element (32) includes a display surface (321) that has a plurality of sub-pixels that are arrayed in a grid along a first direction and a second direction that is substantially orthogonal to the first direction. For each of a plurality of belt-shaped regions that extend across the display surface (321) in the second direction, the optical element (33) regulates the beam direction of image light that is emitted from the sub-pixels. The projection optical system (20) projects image light that has had the beam direction thereof regulated by the optical element (33) and thereby forms a virtual image (51) of the display surface. The driver (36) is controlled by the controller (35) and displaces the optical element (33).
