ABSTRACT:
An exemplary liquid crystal display (200) includes a plurality of gate lines (201), data lines (202), common lines (210), first pixel electrodes (204) and second pixel electrodes (214). Each of areas defined by one of the first pixel electrodes and an adjacent one of the second pixel electrodes is a pixel unit (208). Each pixel unit is driven by a first TFT (203) and a second TFT (213). The first thin film transistor and the second thin film transistor in each pixel unit are connected to a same one of the gate lines and a same one of the data lines, and to the first pixel electrode and the second pixel electrode respectively. A channel width/length ratio of the first thin film transistor is different from a channel width/length ratio of the second thin film transistor.
