Abstract

The present disclosure relates to a display panel. The display panel may include a substrate. The substrate may include a display area, a dummy area inside the display area, and a boundary area between the dummy area and the display area on the substrate. The display substrate may further include an isolation protrusion on the substrate at the boundary area. The isolation protrusion may be configured to isolate a functional layer in the display area from the functional layer in the dummy area, and at least a side surface of the isolation protrusion facing the dummy area may be covered by an isolation inorganic layer.
