The disclosure discloses a GOA circuit and a liquid crystal display. The GOA circuit comprises a plurality of GOA units, each sequentially charging the Nth-staged horizontal scanning lines and the (N+1)th-staged horizontal scanning lines in the display region. The GOA unit comprises N-staged pull-up control circuits, (N+1)-staged pull-up control circuits, N-staged pull-up circuits, (N+1)-staged pull-up circuits, N-staged pull-down circuits, (N+1)-staged pull-down circuits, and a pull-down holding circuit. The pull-down holding circuit holds the voltage level of the Nth-staged gate signal point and the Nth-staged horizontal scanning line to the low level after the Nth-staged horizontal scanning line is charged, and holds the voltage level of the (N+1)th-staged gate signal point and the Nth-staged horizontal scanning line to the low level after the (N+1)th-staged horizontal scanning line is charged. By way of such configuration, the two-staged GOA units share a common pull-down holding circuit to further reduce the power consumption.
