Abstract
The present application provides a display panel and a display device. The display panel comprises a substrate, a dam, a first metal partition structure, a common layer and a cathode. The side surface of the first metal partition structure close to a hole area is provided with a recessed first undercut structure, so as not only to prevent water vapor from laterally invading a display area via the common layer, but also to avoid electrochemical corrosion due to a conductive path formed by the charged cathode overlapping the first metal partition structure.
