Abstract: The present disclosure relates to a display panel and a display device. In the display panel, multiple transfer lines are arranged in a layer different from a layer in which first signal lines are located, and the transfer lines are connected to parts of the first signal lines close to bending sections through transfer holes. Multiple transfer holes are close to an edge of a non-display area along a first direction in sequence and are away from the edge of the non-display area along a second direction in sequence.

Abstract: A display substrate has blocking structures. The display substrate includes a base substrate, a display structure on a display area of the base substrate, at least one blocking structure on a peripheral area around the display area of the base substrate, and a first water-blocking layer on the substrate. The first water-blocking layer may cover the display structure and the at least one blocking structure. The blocking structure may be configured to block cracks generated on the first water-blocking layer at a side of the blocking structure opposite from the display area from propagating to the display area.
