ABSTRACT:
A two TFT pixel structure liquid crystal display includes a first and a second scan line, a first and a second signal line, and a pixel. The pixel includes a pixel electrode and a first and a second transistor. A gate of the first and the second transistor is electrically connected to the first and the second scan line respectively. A source of the first and the second transistor is electrically connected to the first and the second signal line respectively. The drains of the first and the second transistor are electrically connected to the pixel electrode. The ratio of the channel width to the channel length of the first transistor is less than the ratio of the channel width to the channel length of the second transistor.
