Abstract
A display apparatus, a head-up display and a motor vehicle are provided. The display apparatus includes a projector device, a reflector structure and a light beam diffuser structure. Light emitted from the projector device passes through the light beam diffuser structure, is reflected by the reflector structure, and then reaches a first predetermined region; the light beam diffuser structure is configured to diffuse a light beam passing through the light beam diffuser structure; the reflector structure is configured to reflect the light emitted from the projector device and the light reflected by the plurality of sub-reflector structures reaches a second predetermined region within the first predetermined region if the light beam diffuser structure is removed from an optical path from the projector device to the first predetermined region, and an area of the second predetermined region is smaller than an area of the first predetermined region.
