Abstract
A display device including a display panel and an eyepiece is provided. An image realized by the display panel can be provided to a user by passing through the eyepiece. The display device can further include a front quarter-wave plate and a rear quarter-wave plate in order to increase the path of light traveling toward the eyepiece from the display panel. A barrier can be disposed between the front quarter-wave plate and the rear quarter-wave plate. The barrier can reflect or transmit the light traveling toward the eyepiece from the display panel on a region-by-region, so that the loss of light recognized by the user through the eyepiece can be minimized.

A display device comprising:
- a front quarter-wave plate between a display panel and an eyepiece;
- a rear quarter-wave plate between the front quarter-wave plate and the eyepiece;
- a front linear polarizer between the display panel and the front quarter-wave plate;
- a reflective polarizing plate between the rear quarter-wave plate and the eyepiece;
- and
- a barrier between the front quarter-wave plate and the rear quarter-wave plate,
- wherein the barrier includes reflecting regions and transmitting regions between the reflecting regions.
A display device comprising:
- a display panel including pixel regions;
- a front linear polarizer on the display panel;
- a front quarter-wave plate on the front linear polarizer;
- a rear quarter-wave plate on the front quarter-wave plate;
- a reflective polarizing plate on the rear quarter-wave plate;
- an eyepiece on the reflective polarizing plate;
- and
- reflective patterns between the front quarter-wave plate and the rear quarter-wave plate, the reflective patterns exposing a portion of the front quarter-wave plate,
- wherein the pixel regions of the display panel overlap the portion of the front quarter-wave plate exposed by the reflective patterns.
