LIQUID CRYSTAL DISPLAY DEVICE AND DRIVING METHOD THEREFOR

摘要

PROBLEM TO BE SOLVED: To provide a liquid crystal display device and a driving method therefor in accordance with this invention which relates to an active matrix liquid crystal display such as, what is called, AV equipment and OA equipment panel, especially, an active matrix liquid crystal display device with a built-in scanning circuit using poly-silicon TFTs, and which does not generate a defective picture caused by making a gate pulse potential Vg fall at the time of t0. SOLUTION: In P-channel TFTs and n-channel TFTs forming an output amplifier for applying a pulse to a gate line in a vertical scanning circuit, the output capability of the P-channel TFTs is reduced to 50% of that of the n-channel TFTs or less.
