The utility model discloses a display panel and a display device. The display panel is divided into a display area and a non-display area and comprises a substrate, a common bus and a retaining wall,and an active switch for controlling display of the display panel is formed on the substrate; the common bus is formed on the substrate and located in a non-display area of the display panel. The retaining wall is located above the common bus, and the common bus comprises a hollowed-out part and a connecting part surrounding the hollowed-out part. In order to reduce the diffusion of PI (polyimide)liquid out of a common bus, the utility model provides a method for reducing the diffusion of PI liquid out of the common bus. Part of the common bus is hollowed out; forming a plurality of hollows,when PI liquid flows through the common bus, part of PI liquid flows into the hollow part; the hollow part can store part of PI liquid; the PI liquid is prevented from flowing out of the common bus, the buffering effect is achi
