Abstract
A display panel, a manufacturing method, and a display device are provided, which includes following steps: providing a substrate; forming a signal terminal located in the non-display region on the substrate; forming a light-emitting layer located in the display region on the substrate; adopting a mask plate to sequentially form an electron layer and a cathode layer on a side of the light-emitting layer away from the substrate, wherein the electron layer at least covers the display region, and the cathode layer covers the electron layer and extends to the non-display region to connect to the signal terminal.
