Abstract: A display device includes a backlight module, a liquid crystal layer, a lower polarizer, an upper polarizer, and a retardation layer. The liquid crystal layer is disposed on a lighting side of the backlight module while the lower polarizer is disposed between the liquid crystal layer and the backlight module. The upper polarizer is disposed on a side of the liquid crystal layer opposite to the lower polarizer, and the retardation layer is between the upper and lower polarizers. The retardation layer has a retardation area that may modulates the light passing through the lower polarizer and make the light passes through the upper polarizer.
