Abstract
A pixel electrode and a direction control electrode capacitively coupled to the pixel electrode are provided in a pixel. A pixel thin film transistor is connected to a gate line, a data line, and the pixel electrode. A direction control electrode thin film transistor is connected to a previous gate line, a previous data lines or a next data line, and the direction control electrode. The gate lines are supplied with scanning signals, and each scanning signal includes first and second pulses in a frame. The first pulse of a scanning signal is synchronized with the second pulse of a previous scanning signal.
