The invention relates to the technical field of display and particularly relates to a display device, an array substrate and a manufacture method of the array substrate. The array substrate comprises a substrate, a plurality of grid wires and data wires, wherein the grid wires are arranged on the substrate, and the grid wires and the data wires are arranged in an intersecting manner. The array substrate further comprises a plurality of transverse common electrode wires and a plurality of longitudinal common electrode wires, wherein the longitudinal common electrode wires are located below the data wires, and the transverse common electrode wires and the longitudinal common electrode wires are electrically connected. According to the display device, the array substrate and the manufacture method of the array substrate, provided by the invention, through arranging the longitudinal common electrode wires below the data wires, common electrodes in the longitudinal direction are extensively connected, and the overall resistance of the common electrodes is decreased, so that a pixel structure is optimized, and the frame performance of a product is maximally improved. Meanwhile, compared with the prior art, the use of a mask patterning process can be reduced, the production efficiency is increased, and the production cost is reduced.
