ACTIVE MATRIX SUBSTRATE AND DRIVING METHOD THEREOF AND PRODUCTION THEREOF

摘要

PURPOSE:To prevent the generation of a DC offset and to improve the reliability and display quality of a liquid crystal display device by devising the constitution of the active matrix substrate used in the liquid crystal display device, etc., and driving pulse waveforms. CONSTITUTION:The voltage shift occurring in parasitic capacity is prevented by providing n type 31a to 31i and p type 32a to 32i thin-film transistors at the respective picture elements of the active matrix substrate and shifting the timing for turning off the gate pulses of these TFTRs.
