DISPLAY SUBSTRATE, FABRICATION METHOD THEREFOR, AND DISPLAY DEVICE

WIPO Patent Application WO/2022/226686

A1

The present disclosure provides a display substrate, a fabrication method therefor, and a display device. The display substrate comprises a display area, the display area comprising a hole opening area, a first pixel area, and an isolation area. The isolation area is located between the first pixel area and the hole opening area, the isolation area surrounding the hole opening area, and a boundary line between the hole opening area and the isolation area being a cutting line. The display substrate also comprises: a crack barrier structure, a stripping barrier structure, and a packaging structure. The crack barrier structure is located in the isolation area, which comprises a reserved cutting transition area located between the crack barrier structure and the hole opening area. The stripping barrier structure is located in the reserved cutting transition area. The distance L between a side of the stripping barrier structure closest to the hole opening area and the cutting line satisfies: 0 μm≤L≤30 μm. A first part of the packaging structure is located on a side of the stripping barrier structure facing away from a substrate. The stripping barrier structure enables the surface of the display substrate in contact with the first part to be uneven.
