Abstract
A representative display device includes a display module, a polarization controller and a compensator. Each pixel region of the display module has a first sub-pixel region, a second sub-pixel region and a third sub-pixel region respectively providing a first light, a second light and a third light of the same polarization. The polarization controller has control regions that control the polarization of the light passing therethrough. The compensator has first compensating regions, second compensating regions and third compensating regions corresponding to the first sub-pixel regions, the second sub-pixel regions and the third sub-pixel regions, respectively. The compensations of phase retardation of the first light, the second light and the third light generated by passing through the first compensating regions, the second compensating regions and the third compensating regions are different from one another.
