Patent ID: 7633575

Claim:
A liquid crystal display comprising: a plurality of gate lines parallel to each other; and a plurality of data lines parallel to each other and intersecting with the gate lines, every two adjacent gate lines and every two adjacent data lines defining a pixel unit, each pixel unit comprising: a first thin film transistor, a second thin film transistor, a first pixel electrode, and a second pixel electrode, gate electrodes of the first and second thin film transistors being connected to a same one of the gate lines, a source electrode of the first thin film transistor being connected to a corresponding one of the data lines, a drain electrode of the first thin film transistor being connected to the first pixel electrode, a source electrode of the second thin film transistor being connected to the first pixel electrode, and a drain electrode of the second thin film transistor being connected to the second pixel electrode, a channel width/length ratio of the second thin film transistor being such that a voltage of the drain electrode of the second thin film transistor is less than a voltage of the corresponding source electrode when the second thin film transistor is switched on.
