Abstract

This disclosure discloses an array substrate, and a production method, a display panel, and a display apparatus thereof. Particularly, this disclosure proposes a method of producing an array substrate, having the following steps: providing a substrate having a drive transistor region and a switch transistor region thereon; forming an preset layer for active layer on a side of the substrate; patterning the preset layer for active layer to form a drive active layer and a switch active layer, wherein an orthographic projection of the drive active layer on the substrate is located in the drive transistor region, an orthographic projection of the switch active layer on the substrate is located in the switch transistor region, and a carrier concentration in the drive active layer is less than a carrier concentration in the switch active layer.
