Abstract:
1. A display device comprising: a plurality of pixels; a gate driver applying gate signals to the pixels; a data driver applying data voltages to the pixels; and a signal controller outputting a plurality of control signals for controlling the gate driver and the data driver, wherein polarity of a data voltage applied to at least one pixel is changed at least every two frames, each gate signal comprises a gate-off voltage, a first gate-on voltage, and a second gate-on voltage, and the gate driver outputs the second gate-on voltage after a predetermined time has elapsed from the first gate-on voltage, and the first gate-on voltage is outputted only when the polarity of the data voltage applied to the at least one pixel for a frame is opposite to a polarity of a data voltage applied in a previous frame, and the second gate-on voltage is outputted without the first gate-on voltage when the polarity of the data voltage for the frame is equal to the polarity of the data voltage for the previous frame.
