The present disclosure provides an array panel and a method of manufacturing the array substrate and a display device. The array substrate includes: a substrate; a sub-pixel, wherein the sub-pixel is located on the substrate, and the sub-pixel includes a pixel electrode and a common electrode, an orthographic projection of the pixel electrode on the substrate at least partially overlap an orthographic projection of an opening area of the sub-pixel on the substrate, and an orthographic projection of the common electrode on the substrate at least partially overlaps the orthographic projection of the opening area of the sub-pixel on the substrate; and a touch signal line, wherein the touch signal line is located on the substrate, and an orthographic projection of the touch signal line on the substrate partially overlaps the orthographic projection of the opening area of the sub-pixel on the substrate; the touch signal line, the common electrode and the pixel electrode are stacked in sequence along a direction away from the substrate.
