The data lines are disposed in the display area and cross the gate lines. The dummy gate line is disposed adjacent to the last gate line of the gate lines and receives a dummy gate signal transmitted from an external device. Thus, a dummy gate line is adjacent to the last gate line and a pixel electrode connected to the last gate line is affected by a dummy gate signal applied to the dummy gate line.
