A display device can include a display panel including a first gate line and a second gate line; and a gate driving circuit configured to output a first gate signal to the first gate line in synchronization with a first horizontal synchronization pulse, and output a second gate signal to the second gate line in synchronization with a second horizontal synchronization pulse after the first horizontal synchronization pulse, and adjust at least a portion of the first gate signal or at least a portion of the second gate signal so that an area under one pulse of the first gate signal is substantially equal to an area under one pulse of the second gate signal.
