    摘要： A flat panel display device is provided with an increased viewing angle having good dark versus light imaging contrast. The display device includes a display panel, a first optical unit, and a second optical unit. The display panel includes a liquid crystal layer that is driven in a vertical alignment mode. The first optical unit includes a negative C-plate and a first polarizer having a first absorption axis. The second optical unit includes a biaxial compensation plate having a refractive indices coefficient, (nx−nz)/(nx−ny) of more than 0.45 and less than 0.55, and a second polarizer having a second absorption axis crossing the first absorption axis. The biaxial compensation plate has a refractive indices relationship of nx>nz>ny such that dispersion of polarization states of colored light rays passed through the C-plate and the liquid crystal layer may be minimized and gathered about an extinction point, thereby improving contrast at side viewing angles.

    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.

    摘要： In a display panel, main and sub pixel electrodes are connected to first and second drain electrodes of a thin film transistor, respectively, to receive a data voltage during a 1 H period as main and sub pixel voltages. A main storage electrode overlaps the main pixel electrode to receive a first common voltage that varies with the gate pulse and the polarity of the data voltage. A sub storage electrode overlaps the sub pixel electrode to receive a second common voltage that is uniformly maintained at a constant voltage level. The sub pixel voltage is uniformly maintained by the second common voltage, but the main pixel voltage is shifted up or down by the first common voltage. Thus, the main pixel voltage may have a voltage level higher than that of the sub pixel voltage.
