    Abstract: A display device includes: a first coupling-in module configured to couple first image light into a light guide assembly at a preset first incident angle, thereby enabling the first image light to propagate in the light guide assembly by total reflection and to be incident in a coupling-out light-splitting module; a second coupling-in module configured to couple second image light into the light guide assembly at a preset second incident angle, thereby enabling the second image light to propagate in the light guide assembly and to be incident in the coupling-out light-splitting module; a coupling-out light-splitting module configured to, couple the first and second image light out from the light guide assembly to enter a first position area and a second position area of the human eye, respectively. The first and second image light are different light field information of an identical image; and are both collimated light.
