Abstract
In an embodiments of the present invention, since two pixel electrodes are arranged in the pixel unit and each of the pixel electrodes is respectively controlled by a corresponding TFT, the rotation direction of the liquid crystal molecules may be controlled by the voltage difference between the two pixel electrodes, while the voltage on the pixel electrodes of other pixel units in the array substrate is not affected, so that the greenish phenomenon can be avoided. Furthermore, since the two TFTs for controlling the two pixel electrodes respectively may have same parasitic capacitor when the pixel unit is turned off, the voltage difference between the two pixel electrodes is kept unchanged, and thus the occurrence of the image flickering can be avoided.
