Display panel and display device

The invention discloses a display panel and a display device, the display panel is provided with a display area and a non-display area at least partially surrounding the display area, and the display panel comprises a substrate; the array layer is arranged on one side of the substrate, the array layer comprises at least two conductive layers which are arranged in a stacked mode, the conductive layers comprise first conductive layers which are far away from the substrate relative to other conductive layers, and the first conductive layers comprise connecting parts arranged in the non-display area; and the protection part at least covers the side surface of the connecting part. The protection part at least covers the side surface of the connection part of the first conductive layer to protect the side surface of the connection part from being etched by a solvent, so that the problem of overlarge side etching amount of the connection part is solved, and further, the reliability problems of black spots, bright li
