A display device and driving method thereof are provided. In the display device, a control circuit provides first and second start signals. In a display panel, a pixel array has a plurality of odd and even gate lines. A first and second gate circuits respectively receive the first and second start signals, and respectively provide the sequentially enabled first and second gate signals to odd and even gate lines according to the phases of the first and second start signals, respectively. One of the first and second start signals is phase-shifted by at least one clock cycle from a preset phase during a first scan period that scans from a first side to a second side of the pixel array or during a second scan period that scans from the second side to the first side of the pixel array.
