Display panel and display device

The invention discloses a display panel and a display device. The display panel comprises a substrate, a cathode layer located on the substrate, a plurality of first supporting columns and a pluralityof second supporting columns which are supported between the substrate and the cathode layer, a packaging cover plate located on the side, away from the substrate, of the cathode layer, and a touch electrode layer located between the packaging cover plate and the cathode layer. The touch electrode layer comprises a plurality of touch electrodes; the orthographic projection of the first supportingcolumns on the substrate and the orthographic projection of the touch electrodes on the substrate have an overlapped area, and the orthographic projection of the second supporting columns on the substrate and the orthographic projection of the touch electrodes on the substrate have no overlapped area. Through the arrangement of the two types of supporting columns between the substrate and the cathode layer, the types of t
