摘要:
A first pixel electrode and a second pixel are formed in a pixel area. The first pixel electrode is coupled to the second pixel electrode via a coupling capacitance. A voltage is applied to the second pixel electrode from the first pixel electrode through the coupling capacitance. Therefore the voltage applied to the second pixel electrode depends on the voltage applied to the first pixel electrode and the two voltages have a certain ratio. Applying two different voltages in a pixel area can improve display quality.
