Abstract
The present disclosure provides an array substrate and a manufacturing method thereof, and a display panel. In the array substrate, a functional layer disposed between an active layer and a gate insulating layer protects the active layer during etching of the active layer, which prevents the active layer from damage and conducts a source/drain layer and the active layer, so that transistors in the array substrate work normally, solving the technical problem that current display panels damage the active layer during a preparation process, which causes performance of thin film transistors to decrease.
