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.

Abstract: A display panel and a display device, the display panel includes an array substrate; wherein the array substrate includes a common electrode, a first insulation layer, a plurality of pixel electrodes and an alignment layer; the common electrode, first insulation layer, plurality of pixel electrodes and alignment layer are successively arranged; at least one first through hole is defined in the first insulation layer, and the alignment layer contacts with the common electrode via the at least one first through hole. By arranging in such a manner, although a thin-film transistor stays in a turn-on state for an extremely short time, however, since the common electrode is always in a conductive state, so that the electrostatic charge remaining on the alignment layer can be conducted away by the common electrode, thereby reducing the electrostatic charge remaining on the alignment layer, and thus improving display quality of display panel.
