Provided is a driving method for a liquid crystal display device. The method comprises steps of providing a first grid pulse to a first gate wire to drive a first sub-pixel and a second sub-pixel adjacent to each other to execute a charging operation; providing a second grid pulse to a second gate wire to drive a third sub-pixel and a fourth sub-pixel adjacent to each other to execute a charging operation; providing a third grid pulse to a third gate wire to drive a second sub-pixel to execute a charge sharing operation; providing a fourth grid pulse to a fourth gate wire to drive a fourth sub-pixel to execute a charge sharing operation. At least one gate wire is disposed between the first gate wire and the second gate wire. The third gate wire is adjacent to the first gate wire. The fourth gate wire is adjacent to the second gate wire. The first, the second, the third and the fourth grid pulses are triggered in order.
