Embodiments of the present invention disclose a manufacturing method of an array substrate, an array substrate and a display. The manufacturing method comprises: forming a gate electrode of a TFT on a substrate; forming a metal oxide semiconductor thin film and a top metal thin film, and performing a mask process to the metal oxide semiconductor thin film and the top metal thin film, in order to form an active layer opposing the gate electrode and a source electrode and a drain electrode of the TFT respectively; and forming a passivation layer overlying the source electrode and the drain electrode, wherein during the mask process to the top metal thin film, a hydrogen peroxide-based etchant with a pH value between 6 and 8 is used to etch the top metal thin film. |
