description The invention, which belongs to the display field of the liquid crystal display panel, discloses a gate drive circuit of a liquid crystal display panel. With the gate drive circuit, a problem that the drive voltage obtained by the gate drive chip is reduced level by level because of attenuation of the gate drive voltage by the panel edge area and thus displaying of the panel horizontal display area is not uniform according to the existing large-dimension liquid crystal panel can be solved. The gate drive circuit comprises a drive circuit board and gate drive chips, wherein the drive circuit board and the gate drive chips are connected mutually. The gate drive chips connected to the same drive signal output terminal of the drive circuit board are divided into a plurality of chip groups; each chip group is connected to the drive circuit board by a corresponding connecting lead; and the impedance of the connected leads corresponding to the chip groups connected to the same drive signal output terminal of the dri
