A gate driver on array (GOA) circuit of an IGZO thin film transistor and a display device thereof are described. The GOA circuit of the IGZO TFT includes a plurality of cascade GOA units. The GOA unit in the stage N includes a pull-up control unit, a pull-up unit, a pull-down unit, a pull-down holding unit, a transferring unit, a bootstrap capacitor, a first constant voltage with a negative level electrical potential, and a second constant voltage with a negative level electrical potential. The present invention solves the problem of the failure of the GOA circuit in the IGZO TFT. |
