An array substrate, a manufacture method thereof, and a display device with the array substrate are provided. The array substrate includes a substrate; a first gate scanning line; a first gate insulating layer; an active layer; a date scanning line; a pixel electrode formed in a pixel unit defined by the first gate scanning line and the data scanning line and over the data scanning line; and a second gate scanning line formed over or below the first gate scanning line. The second gate scanning line is substantially overlapped with the first gate scanning line in a stacking direction of the array substrate, and is arranged to be insulated from the first gate scanning line, the active layer, the data scanning line, and the pixel electrode, respectively.
