    Abstract: A display device includes a display panel, a data driver, a gate driver, and a controller. The display panel includes a plurality of pixels. The data driver provides data voltages to the plurality of pixels through data lines during an active period of a frame period and provides a blank voltage to the plurality of pixels through the data lines during a blank period of the frame period. The gate driver provides a gate-on voltage to the plurality of pixels through gate lines during the active period and provides a gate-off voltage to the plurality of pixels through the gate lines during the blank period. The controller controls the data driver and the gate driver. The blank voltage increases and the gate-off voltage increases, when a time in the blank period reaches a predetermined time.
