Abstract
A display device is provided. The display device includes a plurality of diffractive optical elements each configured to emit light guided in a light guide plate to a user. Virtual images by the light are observed by the user at two or more different depths according to the plurality diffractive elements.
Claims20
A display device comprising:
- a plurality of diffractive optical elements each configured to emit light guided in a light guide plate,
- wherein a first diffractive optical element, among the plurality of diffractive optical elements, is configured to form a first virtual image based on the light, to be observed at a first depth from a user,
- wherein a second diffractive optical element, among the plurality of diffractive optical elements, is configured to form a second virtual image by the light, to be observed at a second depth from the user, and
- wherein the first depth is different from the second depth.
