Patent ID: 7446763

Claim:
A liquid crystal display comprising: a liquid crystal panel including a plurality of gate lines, a plurality of data lines, and a plurality of pixels, each pixel including a liquid crystal and a switching element connected to one of the gate lines and one of the data lines, and two electrodes selectively forming an electric field in the liquid crystal; a gate driver applying a gate signal to the gate lines, the gate signal including a first voltage for turning on the switching elements and a second voltage for turning off the switching elements; a data driver applying data voltages to the data lines; a signal controller controlling the gate driver and the data driver; and a voltage supplier applying a control voltage substantially equal to one of the first and the second voltages of the gate signal to one of the two electrodes without passing through the switching elements for a control time, the control time being determined based on a reset signal supplied from an external device to the voltage supplier, and wherein the voltage supplier comprises a first switching unit transmitting the first voltage based on the reset signal, and further wherein the first switching unit comprises: a first transistor transmitting a third voltage based on the reset signal; and a second transistor that is turned on by the third voltage to transmit the first voltage.
