Abstract: Disclosed are a display substrate and a display apparatus. The display substrate includes a display region, an opening region located in the display region, and a frame region located between the display region and the opening region. The frame region at least includes a first isolation region, and the first isolation region includes at least one signal line group and at least one organic insulation layer which are stacked. At least two first isolation grooves are disposed in the at least one organic insulation layer, the at least two first isolation grooves are disposed at intervals along a direction away from the opening region, and an orthographic projection of the signal line group in the frame region is located between orthographic projections of the at least two first isolation grooves in the frame region.

Abstract: A display substrate and a manufacturing method therefor, and a display device are provided. The display substrate includes: a base substrate; a planarization layer on the base substrate; an isolation structure and connection pads on the base substrate; and first protective parts on a side of the connection pads away from the base substrate, where the isolation structure includes a first groove formed in the planarization layer, and a first isolation sub-layer and a second isolation sub-layer on a side of the planarization layer away from the base substrate, a first space is provided between the first isolation sub-layer and the second isolation sub-layer, and an orthographic projection of the first space on the base substrate is within an orthographic projection of the first groove on the base substrate; and the first protective parts, the first isolation sub-layer and the second isolation sub-layer are disposed in a same layer.
