Abstract
A display device includes a display panel, a first optical unit, and a second optical unit. The display panel includes a first substrate, a second substrate, and a liquid crystal layer disposed between the first substrate and the second substrate. The liquid crystal layer is operated in a vertical alignment mode. The first optical unit includes a C-plate and a first polarization plate having a first absorption axis. The second optical unit includes a positive A-plate, a negative A-plate, and a second polarization plate having a second absorption axis substantially perpendicular to the first absorption axis. The positive A-plate and the negative A-plate may gather dispersed polarization states of a colored light.
