Abstract
A display device is disclosed, and the display device includes a display layer and a lens layer; the lens layer is provided on a light emergent side of the display layer, and includes at least one grating compound lens unit; the display layer includes at least one display pixel set, and the display pixel set is configured to emit light for imaging toward the grating compound lens unit during display; the grating compound lens unit is configured to optically image the display pixel set; and the grating compound lens unit is further configured to deflect the light for imaging, to make an image-space central visual field direction of the grating compound lens unit intersect with an extension direction of an optical axis of the grating compound lens unit, so that the display device has one or more viewpoints.
