Abstract
An array substrate and a manufacturing method therefor, and a display panel are provided. The manufacturing method includes: forming a scan line and a gate on a substrate; forming a first insulating layer covering the scan line and the gate on the substrate; forming a metal oxide semiconductor layer above the first insulating layer, the metal oxide semiconductor layer including a source, a drain and an active layer; coating an upper surface of the metal oxide semiconductor layer with a photosensitive material layer; photoetching the photosensitive material layer from the back side of the substrate by using a first metal layer as a mask to form a channel protection layer; performing conductorization treatment on the metal oxide semiconductor layer to enable the source and the drain to be conductive; forming a data line above the first insulating layer; and forming a pixel electrode above the first insulating layer.
