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.

Abstract: A display device having an eyepiece is provided. The display device includes a display panel and an eyepiece. An image realized by the display panel may be provided to user through the eyepiece. An optical module may be disposed between the display panel and the eyepiece in order to increase a path of light. For example, the optical module may include a front quarter-wave plate, a half-mirror, a rear quarter-wave plate and a linear reflective polarizing plate, which are sequentially stacked. A positive C-plate may be disposed in the optical module. The light travelling toward the eyepiece from the display panel may pass through the positive C-plate. Thus, in the display device, the overall thickness may be reduced, and the viewing angle may be increased.

Abstract: A display device including a display module and an eyepiece lens is provided. A user can view an image realized by the display module through the eyepiece lens. In the display play according to the present disclosure, a path of a light moving from the display module to the eyepiece lens may be increased by a half-mirror and a reflective polarizing plate which are located between the display module and the eyepiece lens. Thus, in the display device according to the present disclosure, the overall thickness may be decreased without degrading the quality of the image realized by the display module.
