摘要： The present disclosure discloses a GOA gate driving circuit includes a plurality of GOA driving units arranged in cascade, each level GOA driving unit includes a pull-up control part, a pull-up part, a first pull-down part and a pull-down holding part; wherein, each stage GOA driving unit further includes a second pull-down part coupled between the gate control signal and the reference low level signal, the second pull-down part being controlled by a pull-down signal for lowering the gate control signal to the reference low level signal; the phase of the pull-down signal lags behind the latter two-stage scan driving signal, and the pull-down signal is provided by a separate control chip. The present disclosure further discloses a liquid crystal display including a GOA gate driving circuit as described above.
