DRIVE CIRCUIT, DISPLAY DEVICE PROVIDED WITH SUCH DRIVE CIRCUIT AND METHOD FOR DRIVING DISPLAY DEVICE

摘要

When an output signal (Q) of a flip-flop (11) is inactive in a shift register (1), NAND circuits (15a, 15b) of clock pulse extracting sections (13a, 13b) are prevented from performing conduction switching in accordance with periodic level change of clock signals (CK, CKB) between a logical derivation path for high output and a logical derivation path for low output by input of the output signal (Q).
