Abstract:
According to one embodiment, a display device includes a display module which emits display light, an optical element which transmits or reflects the display light, and a reflective element which retroreflects the display light reflected from the optical element. The reflective element includes a first reflector including a first retroreflective surface having retroreflective properties, a first end portion, and a second end portion which is more separated from the optical element than the first end portion, and a second reflector including a third end portion, which overlaps the second end portion and is closer to the optical element than the second end portion, and a second retroreflective surface having retroreflective properties.
