摘要：
A common voltage adjustment circuit (1) of a liquid crystal display panel, and a liquid crystal display device. The common voltage adjustment circuit (1) of a liquid crystal display panel is used for adjusting a first common voltage loaded onto a liquid crystal display panel (2) and comprises an acquisition unit (10), a control unit (30), a feedback unit (50), and an operation regulation unit (70), wherein the acquisition unit (10) is used for acquiring a common voltage on the liquid crystal display panel (2) as a second common voltage, the control unit (30) is used for receiving the second common voltage and transmitting a control signal according to the difference value between the second common voltage and a standard common voltage, the feedback unit (50) outputs a corresponding feedback voltage under the control of the control signal, and the operation regulation unit (70) is used for adjusting the first common voltage according to the feedback voltage and outputting the adjusted first common voltage.
