A display apparatus includes a plurality of pixels connected to a plurality of gate lines and a plurality of data lines and a timing controller, in which each pixel includes a first sub-pixel and a second sub-pixel. In such a display apparatus, the timing controller provides the first sub-pixel and the second sub-pixel with a first data signal and a second data signal corresponding to one of a high gray scale curve and a low gray scale curve, alternately every frame, when the image signal is a first type of image signal, and the timing controller provides the first sub-pixel with a first data signal corresponding to the high gray scale curve and the second sub-pixel with a second data signal corresponding to the low gray scale curve when the image signal is a first type of image signal.
