Display panel and display device

The invention provides a display panel and a display device, the display panel comprises a substrate and a first retaining wall and a second retaining wall which are arranged on one side of the substrate, the first retaining wall is provided with a convex part and/or a concave part, the convex part or the concave part is used for preventing a first packaging layer from extending and jumping over the first retaining wall, and the convex part or the concave part is used for preventing the first packaging layer from extending and jumping over the first retaining wall in the direction perpendicular to the plane where the substrate is located. The orthographic projection of the end part of the second packaging layer along the first direction is provided with a convex part and/or a concave part, so that the arrangement of the end part of the second packaging layer is beneficial to the subsequent formation of a touch terminal, the influence of the material of the second packaging layer on the metal connection during
