Abstract: An array substrate, a method for fabricating the same, and a display device are provided. A metal shielding layer is electrically connected with a common electrode. A first connection part used for electrically connecting the metal shielding layer and the common electrode is arranged in the same layer as a source/drain electrode, and is electrically connected with the metal shielding electrode by means of a via penetrating the first insulating layer and the buffer layer. A storage capacitor is formed between an active layer and the metal shielding layer, increasing capacitance of the array substrate. The first connection part and the source/drain electrode which are arranged in the same layer can be formed by performing a patterning process once, thus reducing the fabricating flow, simplifying the fabricating process, saving the fabricating cost, and decreasing the fabricating time.
