AI Technical Summary
Technical Problem
The film layer on existing display substrates is prone to peeling or cracking near the bending area.
Method used
The inorganic insulating layer of the circuit structure layer is removed in the bending area of the display substrate to form a bending opening. The boundary of the bending opening is covered by the protective structure of the protective structure layer to disperse the stress of the inorganic insulating layer in the circuit structure layer.
Benefits of technology
It effectively prevents the film layer from peeling off and cracking near the bending area, and improves the bending resistance of the display substrate.

Abstract
The embodiment of the utility model provides a display substrate and a display device. The display substrate comprises a display area and a first frame area located on at least one side, a circuit structure layer and a protection structure layer are sequentially arranged on one side of the substrate, a protection structure is arranged in the protection structure layer, the first frame area comprises a bending area, in the bending area, an inorganic insulating layer in the circuit structure layer is removed to form a first bending opening, and the inorganic insulating layer in the circuit structure layer is removed to form a second bending opening. The orthographic projection of at least one boundary of the first bending opening on the substrate is covered by the orthographic projection of the protection structure on the substrate, and the protection structure and the at least one boundary of the first bending opening are located on at least one side of the bending area in the direction pointing to the first frame area along the display area. According to the technical scheme provided by the embodiment of the invention, the technical problem that the film layer near the bending area falls off or cracks are generated can be solved to a certain extent.
