Abstract
A display device includes a display panel having a plurality of pixels respectively connected to a plurality of gate lines and a plurality of data lines, a gate driving circuit that outputs a plurality of gate signals to the plurality of gate lines, and a data driving circuit configured that outputs a plurality of data signals for driving the plurality of data lines. Each of the plurality of pixels includes a first sub-pixel configured to receive a corresponding data signal among the plurality of data signals in response to a first gate signal among the plurality of gate signals, and a second sub-pixel configured to receive a corresponding data signal among the plurality of data signals in response to the first gate signal, and reduce a voltage of the received data signal in response to a second gate signal among the plurality of gate signals. The second gate signal is a signal delayed by a 2×d×H time relative to the first gate signal (where each of d and H is a positive integer, H is a horizontal period, and d×H is a pulse width of first and second gate signals).
