A scanning drive circuit (1) and a liquid crystal display device. The scanning drive circuit (1) comprises: an input module (100) which performs an operation on a higher-level control signal (Q(N-1)) and first and second clock signals (XCK1, CK1) to obtain a first control signal; a reset module (200) which performs zero clearing on a control signal point (Q(N)) according to a reset signal (Reset); a latching module (300) which performs an operation on the first control signal and the first and second clock signals (XCK1, CK1) to obtain a second control signal; a logical processing module (400) which performs a logical operation on the second control signal and a third clock signal (CK2) to obtain a logical control signal; an output module (500) which performs an operation on the logical control signal to obtain a scanning drive signal; and a scanning line (Gate) which receives the scanning drive signal and transmits same to a pixel unit. In this way, the resetting and zero clearing of a control signal point (Q(N)) and a scanning drive signal are achieved, thereby avoiding a failure of a scanning drive circuit (1). |
