Abstract
According to one embodiment, a display device includes first and second retroreflective elements which retroreflect incident light, an optical element which is located between the first retroreflective element and the second retroreflective element, and includes a first surface facing the first retroreflective element and a second surface facing the second retroreflective element and a display unit which is located on a side facing the first surface and emits display light.
Claims17
A display device comprising:
- first and second retroreflective elements which retroreflect incident light;
- an optical element which is located between the first retroreflective element and the second retroreflective element, and comprises a first surface facing the first retroreflective element and a second surface facing the second retroreflective element;
- and
- a display unit which is located on a side facing the first surface and emits display light, wherein
- the optical element includes a first polarizing element comprising the first surface, and a second polarizing element comprising the second surface and spaced apart from the first polarizing element, and
- the first and second polarizing elements comprise a transmission axis which transmits first linearly polarized light and reflects second linearly polarized light intersecting the transmission axis.

A display device comprising:
- a first optical element which comprises a transmission axis transmitting first linearly polarized light, and reflects second linearly polarized light intersecting the transmission axis;
- a display unit which emits the first linearly polarized light and the second linearly polarized light toward the first optical element;
- a second optical element which retroreflects the second linearly polarized light reflected on the first optical element, and modulates the second linearly polarized light reflected on the first optical element into the first linearly polarized light;
- and
- a third optical element which retroreflects the first linearly polarized light having passed through the first optical element, and modulates the first linearly polarized light having passed through the first optical element into the second linearly polarized light.
