    摘要: 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.

    摘要: In a display apparatus, pixels are arranged in a matrix defined by gate lines and data lines, and each pixel includes a first sub pixel charged to a first pixel voltage and a second sub pixel charged to a second pixel voltage having a same voltage level as the first pixel voltage. A voltage controller controls a voltage level of the first and second pixel voltages charged in the pixels corresponding to the first through penultimate pixel rows in response to a next gate signal. A dummy voltage controller controls a voltage level of the first and second pixel voltages charged in the pixels corresponding to the last pixel row in response to a dummy gate signal. Where a dummy voltage controller is not included, a black matrix partially covers the efficient display area of the pixels corresponding to the last pixel row.
