Abstract: An array substrate, a manufacturing method thereof and a display device are disclosed. The array substrate comprises a plurality of pixel unit regions each including a thin-film transistor (TFTs) and a pixel electrode. A first insulating layer provided with a first through hole and a second through hole is formed between an active layer of the TFT and the pixel electrode. A source electrode of the TFT is connected with the active layer through the first through hole. A drain electrode of the TFT is lapped onto the pixel electrode and connected with the active layer through the second through hole. The array substrate can prevent the oxidization of metal such as copper in the process of patterning a transparent conductive film.
