Abstract: An array substrate, a display panel and a display device, including at least two gate lines in a display area, a gate driving circuit and at least two gate fan-out lines in a non-display are described. One end of each of the gate fan-out lines are electrically connected with one signal output of the gate driving circuit and the other end of each of the gate fan-out lines are electrically connected with the gate lines. By configuring a first gate fan-out line of the gate fan-out lines and the gate driving circuit to have an overlapping area outside a mutual connection area, an area where the gate fan-out lines are overlaps the gate driving circuit, space occupied by the first gate fan-out line outside the gate driving circuit is decreased to shorten a distance between the gate driving circuit and the display area.

Abstract: An array substrate and a display panel are provided. The array substrate includes a non-display area and a display area. The non-display area includes a first non-display area and a second non-display area, and the display area includes a normal display area and a wiring area. The normal display area is surrounded by the first non-display area, the wiring area is surrounded by the normal display area, and the second non-display area is surrounded by the wiring area. The second non-display area comprises an opening area. In the solution, since the number of data lead lines in the same layer in the wiring area is reduced, a line distance between adjacent data lead lines is increased, thereby reducing coupling capacitance between adjacent data lead lines arranged in the same layer.
