Disclosed are an array substrate and a display device. The array substrate includes: a plurality of sub-pixel elements in an array, wherein each row of sub-pixel elements includes a common electrode; the common electrode includes a plurality of sub-common electrodes, each of which corresponds to one of the sub-pixel elements; the sub-common electrode includes a body connection section, a plurality of comb teeth connected with the body connection section, and a shielding section connected with the body connection section, wherein the first comb teeth and the shielding section are on the same side of the body connection section, and the shielding section is on the outermost side of the first comb teeth; and the body connection sections of two adjacent sub-common electrodes in the common electrode are on two opposite sides. The body connection sections of two adjacent sub-common electrodes in each common electrode are arranged on two opposite sides.
