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.
