Patent ID: 7570241

Claim:
A liquid crystal display device, comprising: first and second gate lines; first and second data lines; first and second common voltage switching devices, the first common voltage switching device supplying one of a first common voltage and a second common voltage, the second common voltage switching device supplying the other of the first common voltage and the second common voltage, wherein a value of the first common voltage is different than a value of the second common voltage; a first thin film transistor connected to the first data line and the first gate line; a second thin film transistor connected to the second data line and the second gate line; a third thin film transistor connected to the second data line and the first gate line; a fourth thin film transistor connected to the first data line and the second gate line; a first liquid crystal capacitor connected to the first thin film transistor and the first common voltage switching device except the second common voltage switching device; a second liquid crystal capacitor connected to the second thin film transistor and the first common voltage switching device; a third liquid crystal capacitor connected to the third thin film transistor and the second common voltage switching device except the first common voltage switching device; and a fourth liquid crystal capacitor connected to the fourth thin film transistor and the second common voltage switching device.
