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