    Abstract: A display apparatus includes a display panel, a gate driver, a data driver and a driving controller. The display panel is configured to display an image based on input image data. The gate driver is configured to output gate signals to gate lines of the display panel. The data driver is configured to output data voltages to data lines of the display panel. The driving controller includes a first compensation lookup table and a second compensation lookup table which are configured to compensate the input image data. The driving controller is configured to select one of the first compensation lookup table and the second compensation lookup table based on a first color shift and a second color shift and to apply the selected one of the first compensation lookup table and the second compensation lookup table to the input image data.

    Abstract: A liquid-crystal display device includes a first substrate, a plurality of pixel units disposed on the first substrate, a color filter layer overlapping the plurality of pixel units and including first to third color filters, a second substrate facing the first substrate, and a liquid-crystal layer interposed between the first substrate and the second substrate. Each of the pixel units of the plurality of the pixel units includes a first pixel, a second pixel and a third pixel. The first pixel includes a first pixel electrode, the second pixel includes a second pixel electrode, and the third pixel includes a first sub-pixel electrode and a second sub-pixel electrode. A voltage applied to the first sub-pixel electrode is different from a voltage applied to the second sub-pixel electrode.
