Abstract: A display device includes a data driver (102), which generates a data voltage to be charged to subpixels of first to fourth colors, inverts a polarity of the data voltage in a cycle of a previously set period, and supplies the data voltage to data lines (S1-Sm), and a gate driver (104) supplying a gate pulse synchronized with the data voltage to gate lines (G1-Gn). A pixel array includes subpixels of the first color, subpixels of the second color, subpixels of the third color, and subpixels of the fourth color. The data driver (102) sequentially generates data voltages of the first to fourth colors at a first polarity, inverts the first polarity of the data voltage of the first color to a second polarity, and sequentially generates the data voltages of the first to fourth colors at the second polarity.
