The present invention provides a liquid crystal display panel and a gate drive circuit thereof. The gate drive circuit comprises a plurality of shift register circuit, and the plurality of shift register circuit are series cascade connected, and each shift register circuit comprises: a first pull-up holding circuit, coupled to the first node, the first clock signal, a first reference voltage and a second reference voltage, and employed to keep a low voltage level of the first node; a compensating circuit, coupled to the first node or the first pull-up holding circuit, and employed to compensate the voltage level of the first node or the first pull-up holding circuit. Thereby, the stability of long-term operation of the gate drive circuit can be promoted to raise the quality of the display panel.
