Publication number: 20210278668Abstract: The invention relates to a near eye display device. A first waveguide element includes first light splitting elements for splitting an image beam, an inclined surface, and an antireflection structure. The image beam enters the first waveguide element from a first light input surface. The image beam, after being reflected by the inclined surface, is transmitted to the first light splitting elements and leaves the first waveguide element from a first light output surface.
