An array substrate, a fabricating method thereof and a display device, the fabricating method comprises forming a plurality of touch electrodes on a base substrate, a plurality of touch electrode leads for leading out signals of the touch electrodes and an array structure comprising a plurality of conducting structures. At least part of touch electrode leads and at least one of the conducting structures are disposed in a same layer and made from a same material. The fabricating method can reduce the amount of masks used in the fabricating process of the array substrate.
