Abstract
This disclosure discloses a display device and a GOA circuit thereof. The GOA circuit includes a plurality of thin film transistors, and the thin film transistors are disposed on a substrate, and the thin film transistor includes at least a metal shading layer and a semiconductor layer sequentially arranged on the substrate, and the metal shading layers of the plurality of thin film transistors are all input in ground signal. This disclosure can avoid the coupling effect of the metal shading layer and ensure the normal output signal of the GOA circuit.
