1. A display device, comprising:
an optical imaging apparatus comprising an image source element, a beam splitting element and a reflective element configured to be aligned on a light path, light emitted by the image source element being reflected by the beam splitting element to the reflective element, the light being reflected by the reflective element to the beam splitting element, and the light being transmitted by the beam splitting element, wherein the image source element comprises an image projection area configured to generate and project imaging light for generating a display image in a scene to be displayed and non-imaging light in the scene to be displayed; and
an absorbing element having a shape and an arrangement position in the display device to enable the absorbing element to absorb the non-imaging light, and not block the imaging light,
wherein the absorbing element comprises a first absorbing element attached to an edge portion of the image source element adjacent to a human eye position and extending toward the beam splitting element.
