Title:
DISPLAY SUBSTRATE AND MANUFACTURING METHOD THEREFOR, AND DISPLAY DEVICE
Document Type and Number:
WIPO Patent Application WO/2020/187151
Kind Code:
A1
Abstract:
A display substrate and manufacturing method therefor, and a display device, for preventing signal wiring (0121) of a wiring layer (012) of a flexible display substrate (011) from being broken. The display substrate (01) comprises: a flexible base substrate (011), and a wiring layer (012), a first adhesion enhancement layer (013) and a first insulating layer (014) stacked on the flexible base substrate (011). The first adhesion enhancement layer (013) is located between the first insulating layer (014) and the wiring layer (012), and the first adhesion enhancement layer (013) is separately adhered to the first insulating layer (014) and the wiring layer (012); the flexible base substrate (011) comprises a bending area (A1); an overlapping area exists between the orthographic projection of the first adhesion enhancement layer (013) on the flexible base substrate (011) and the bending area (A1); the orthographic projection of signal wiring (0121) of the wiring layer (012) on the flexible base substrate (011) is partially located in the bending area (A1).
