Array substrate and manufacturing method, and display apparatus

The invention provides a manufacturing method of an array substrate. The method comprises the following steps: forming a graph including a pixel electrode; and then forming a graph including an active layer. Correspondingly, the invention also provides the array substrate and a display apparatus. During a array substrate manufacturing process, an conductive object is not left on the active layer so that generation of a leakage current is reduced, quality of the array substrate is increased and a display effect of the display apparatus is improved.
