A display device includes a display panel, a scan driver, a first data driver, a second data driver, and a timing controller. The display panel includes a plurality of pixels. The scan driver supplies scan signals to the pixels. The first data driver is connected to first ends of data lines and supplies data voltages to the pixels through the data lines during an active period of the scan signals. The second data driver is connected to second ends of the data lines and supplies the data voltages to the pixels through the data lines during the active period of the scan signals. The timing controller controls the scan driver and the first and second data drivers. The first and second data drivers swap at least two of the data voltages based on a swap control signal.
