Abstract
According to one embodiment, a display device includes an optical element which transmits or reflects incident light, and a first reflective element including a first reflective portion and a second reflective portion. The first reflective portion retroreflects reflective light reflected on the optical element. The second reflective portion has an area less than an area of the first reflective portion and regularly reflects the reflective light.
Claims20
A display device comprising:
- an optical element which transmits or reflects incident light;
- and
- a first reflective element comprising a first reflective portion which retroreflects reflective light reflected on the optical element, and a second reflective portion which has an area less than an area of the first reflective portion and regularly reflects the reflective light.
A display device comprising:
- an optical element which transmits or reflects incident light;
- and
- a first reflective element comprising a first reflective portion which has an uneven surface with respect to a first plane and retroreflects reflective light reflected on the optical element, and a second reflective portion which regularly reflects the reflective light, wherein
- the first reflective portion comprises first, second and third reflective surfaces being in contact with each other at a central point,
- the first reflective surface is adjacent to the second and third reflective surfaces,
- the second reflective surface is adjacent to the first and third reflective surfaces,
- the third reflective surface is adjacent to the third and first reflective surfaces,
- the second reflective portion is provided in first, second and third regions comprising a flat surface parallel to the first plane,
- the first region is adjacent to the first and second reflective surfaces,
- the second region is adjacent to the second and third reflective surfaces, and
- the third region is adjacent to the third and first reflective surfaces.
