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.
