ABSTRACT:
A liquid crystal display device and a driving method for a liquid crystal display. The liquid crystal display device is formed to have thin film transistor conductive channels having an inverted “U”-shape. A shielding plate is provided to block incident light from reaching the conductive channels of the thin film transistors. This reduces or eliminates photo-induced leakage current and picture quality degradation. To prevent pixel electrode potential fluctuations caused by subsequent scan line drive signals, the liquid crystal display device is driven by scan signals that are sequentially applied from the mth gate line up to the first gate line.
