Abstract:
The present invention relates to a liquid crystal drive display device, including a display area and a liquid crystal drive circuit, the liquid crystal drive circuit including a plurality of stage GOA circuits, each stage GOA circuit includes a signal line and an auxiliary pull-down circuit, wherein the signal lines are divided into odd-numbered signal lines and even-numbered signal lines, the auxiliary pull-down circuits are divided into first auxiliary pull-down circuits and second auxiliary pull-down circuits; wherein the odd-numbered signal lines and the even-numbered signal lines are separately located on two sides of the display area, and the first auxiliary pull-down circuits and the second auxiliary pull-down circuits are also separately located on two sides of the display area, any two adjacent stage GOA circuits of the plurality of stage GOA circuits share the first auxiliary pull-down circuits and the second auxiliary pull-down circuits.
