Abstract
The present invention provides an array substrate, a manufacturing method thereof, and a display panel. Orthographic projections of channel layers of two types of thin film transistors in a design of a driving circuit on the array substrate at least partially overlap, that is, two thin film transistors are stacked on top of each other, thereby facilitating a narrow border design of the display panel. In addition, a channel layer of one of the thin film transistors is an amorphous oxide semiconductor layer, which can reduce node leakage in the driving circuit, which is conducive to improving circuit stability and reducing power consumption.
