A gate driver sequentially supplies first and second gate signals to gate lines. First and second switching parts are located in an ithhorizontal line and supply video signals from data lines to LC cells by the control of an ithgate line. Third switching parts supply video signals to the cells located in the horizontal line, and are connected to the same data line as the second switching part, and are controlled by the ithand an i−1thgate lines. Fourth switching parts supply video signals to the cells located in the horizontal line and are connected to the same data line as the first switching part, and are controlled by the ithand i−1thgate lines.
