A gate driver on array (GOA) circuit and liquid crystal display. The GOA circuit comprises multiple GOA units. Each of the GOA units sequentially charges an Nth-stage horizontal scan line G(N) and an N+1th-stage horizontal scan line G(N+1) of a display region. The GOA unit comprises: an Nth-stage pull-up control part (101), an N+1th-stage pull-up control part (102), an Nth-stage pull-up part (201), an N+1th-stage pull-up part (202), an Nth-stage key pull-down part (301), an N+1th-stage key pull-down part (302), and a pull-down holding part (400). Upon the Nth-stage horizontal scan line G(N) is charged, the pull-down holding part (400) holds the potentials of an Nth-stage gate signal point Q(N) and the Nth-stage horizontal scan line G(N) at a low potential. Upon the N+1th-stage horizontal scan line G(N+1) is charged, the pull-down holding part (400) holds the potentials of an N+1th-stage gate signal point Q(N+1) and the N+1th-stage horizontal scan line G(N+1) at a low potential. The present invention enables two stages of a GOA unit to share the same pull-down holding part (400), thus reducing power consumption. |
