Provided are a gate driver on array (GOA) circuit, an array substrate, and a display device. The GOA circuit provides a scanning pulse signal to a pixel matrix and includes cascaded GOA units. The GOA unit includes first and second enable input terminals, first and second output terminals, and a first node. The first output terminal of an N−2-level GOA unit is connected to the first enable input terminal of an N-level GOA unit, and the second output terminal of the N−2-level GOA unit is connected to the second enable input terminal of an N−1-level GOA unit, N being greater than 2. The second output terminal outputs a scanning pulse signal to the pixel matrix. The GOA unit further includes a pull-up unit connected to the second enable input terminal and the first node to charge the first node to a first given voltage.
