The present disclosure provides an array substrate, a display panel and a display device. The array substrate includes a first conductive pattern and a second conductive pattern forming a ground (GND) protection circuit. The first conductive pattern includes a plurality of first conductive segments spaced apart from each other, and adjacent first conductive segments are connected to each other by the second conductive pattern, an insulating layer is arranged between the first conductive segments and the second conductive pattern, and the first conductive segments are connected to the second conductive pattern through via holes penetrating through the insulating layer. In addition, the present disclosure provides a display panel including the above array substrate. Furthermore, the present disclosure provides a display device including the above array substrate.
