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.

Claims (12)

1. A liquid crystal display comprising:

a plurality of first signal lines transmitting scanning signals;

a plurality of second signal lines transmitting data voltages; and

a plurality of first and second pixels connected to the first and the second signal lines,

wherein each of the first pixels has a first pixel electrode, a first direction control electrode, a first thin film transistor having a gate electrode connected to a relevant first signal line, a source electrode connected to a relevant second signal line, and a drain electrode connected to the first pixel electrode, and a second thin film transistor having a gate electrode connected to a previous first signal line or a next first signal line, a source electrode connected to a next second signal line, and a drain electrode connected to the first direction control electrode; and

wherein each of the second pixels has a second pixel electrode, a second direction control electrode, a first thin film transistor having a gate electrode connected to the previous first signal line, a source electrode connected to the relevant second signal line, and a drain electrode connected to the second pixel electrode, and a second thin film transistor having a gate electrode connected to a previous first signal line previous to the previous first signal line, a source electrode connected to the relevant second signal line, and a drain electrode connected to the second direction control electrode.

2. The liquid crystal display of claim 1 , wherein the liquid crystal display is subjected to a double-dot inversion and each scanning signal has first and second pulses in a frame.

3. The liquid crystal display of claim 2 , wherein the first pixels form a plurality of first pixel rows and the second pixels form a plurality of second pixel rows.

4. The liquid crystal display of claim 3 , wherein the first pixel rows and the second pixel rows are alternately arranged.

5. The liquid crystal display of claim 4 , wherein adjacent two of the first and the second pixel rows are supplied with data voltages having equal polarity in pairs and a first pixel row in each pair is supplied with a scanning signal prior to a second pixel row in the pair.

6. The liquid crystal display of claim 2 , wherein the first pulse in a scanning signal is synchronized with the second pulse in a previous scanning signal.

7. The liquid crystal display of claim 1 , wherein each of the first and second pixel electrodes has a cutout overlapping one of the direction control electrodes at least in part.
