Abstract

A display substrate, a display panel, and a display apparatus are provided. The display substrate includes a display area and a non-display area on at least one side of the display area, the non-display area including at least a retaining-wall area, a crack-blocking area, and a cut-retention area in a direction away from the display area. The display substrate includes a base substrate, an insulating layer, a first inorganic layer, and a first dummy metal layer. The insulating layer is on the base substrate, to form a blocking-area raised layer in the crack-blocking area. The first inorganic layer is on the insulating layer and at least partially covers the blocking-area raised layer, and the first inorganic layer is formed with a first slope and a second slope corresponding to opposing sides of the blocking-area raised layer, respectively, the first slope being closer to the display area than the second slope. The first dummy metal layer is in the non-display area and covers at least a portion of the first slope and at least a portion of the second slope.
