Patent ID: 7507992

Claim:
A liquid crystal display device, comprising: a first pixel including a first thin film transistor, the first thin film transistor having a first channel W/L (width/length) ratio and a first gate-drain parasitic capacitance; a second pixel including a second thin film transistor, the second thin film transistor being disposed at a different relative position than the first thin film transistor, the second thin film transistor having a second channel W/L (width/length) ratio and a second gate-drain parasitic capacitance; and a third pixel including a third thin film transistor, the third thin film transistor being disposed at a different relative position than the first and second thin film transistors, the third thin film transistor having a third channel W/L (width/length) ratio and a third gate-drain parasitic capacitance, wherein the first, second, and third channel W/L ratios are substantially the same, and the first gate-drain parasitic capacitance has a value between the second and third gate-drain parasitic capacitances in order that common voltages for normal operation of the first, second, and third pixels can be substantially the same, and wherein a gate electrode of each of the first to third thin film transistors is a portion of a gate line, wherein source and drain electrodes of the second thin film transistor are shifted along a width of the gate line with respect to a position of source and drain electrodes of the first thin film transistor, and wherein source and drain electrodes of the third thin film transistor are shifted opposite to the shifted direction of the source and drain electrodes of the second thin film transistor.
