Abstract:
1. A method of driving a liquid crystal display device comprised of gate lines G 1 through G M , comprising: providing gate lines G providing data lines arranged at regular intervals so as to cross the gate liens; providing a thin film transistor in an unit liquid crystal cell defined by the gate lines and the data lines, wherein the thin film transistor includes a gate electrode that extends in a predetermined direction from the gate line, a semiconductor layer over the gate electrode, a source electrode that extends over the semiconductor layer from the date line and a drain electrode, wherein a conductive channel has an inverted “U” shape and wherein light at an incident direction of the inverted “U” shaped conductive channel is blocked by a shielding plate over an upper portion of the thin film transistor; providing a storage capacitor for the thin film transistor on a pth gate line, wherein the storage capacitor includes a first electrode that is part of a p+1th gate line, a gate insulation film and a storage electrode that is connected to a pixel electrode over the p+1th gate line; and sequentially applying a gate signal voltage pulse to the p+1 gate line, the pth gate line and a p−1 gate line, wherein p+1 is less than or equal to M(M=2, 3 . . . interger), and wherein p−1 is greater than or equal to 1.
