An LCD panel includes multiple gate lines, and a gate drive circuit connected with the gate lines. The gate drive circuit includes multiple shift register units which are used for outputting shifting signals to sequentially drive all gate lines; each shift register unit includes a first output interface and a second output interface which are connected with adjacent two gate lines. The first output interface outputs a first gate signal, the second output interface outputs a second gate signal; and a duration of the second gate signal is two times of a duration of the first gate signal in a scanning period.
