Abstract
A display device includes a display panel, and a depth perception adjusting unit for adjusting a depth perception, based on polarization characteristics of light output from the display panel, wherein the depth perception adjusting unit includes a directional mirror and a reflective polarizer. Thus, the display device is implemented such that the directional mirror transmits or reflects light depending on an advancing direction of the light. Accordingly, any crosstalk phenomenon does not occur, and a depth perception can be adjusted without any loss of brightness efficiency.
