Abstract
A manufacturing method of an array substrate and a display panel are disclosed. The manufacturing method includes: disposing a photoresist on an active switch; disposing a protective layer on the active switch; disposing a pixel electrode layer on the protective layer. The step of etching each film layer material based on the photoresist to form an active switch includes: performing a first wet etching on the active switch; performing a first dry etching and two ashing treatments on the active switch; performing a second wet etching on the active switch; and removing the photoresist. The present application can improve the issue of photoresist residues.
