Title:
DISPLAY SUBSTRATE AND DISPLAY DEVICE
Document Type and Number:
WIPO Patent Application WO/2023/098285
Kind Code:
A1
Abstract:
A display substrate and a display device. The display substrate comprises a base substrate (01) and a plurality of sub-pixels (10), wherein each sub-pixel (10) comprises a light-emitting element (100), the light-emitting element (100) comprises a light-emitting functional layer (130), and the light-emitting functional layer (130) comprises a plurality of film layers. The display substrate further comprises an isolation structure (600), wherein the isolation structure (600) is arranged between adjacent sub-pixels (10), the isolation structure (600) comprises a first sub-isolation structure (610) and a second sub-isolation structure (620), which are stacked, the first sub-isolation structure (610) is located between the second sub-isolation structure (620) and the base substrate (01), and the size of the first sub-isolation structure (610) is smaller than that of the second sub-isolation structure (620), such that the second sub-isolation structure (620) comprises a protruding portion; or, a slope angle of a side surface of the first sub-isolation structure (610) is greater than 60 degrees and less than 120 degrees, and/or, a slope angle of a side surface of the second sub-isolation structure (620) is greater than 60 degrees and less than 120 degrees; and at least one of the plurality of film layers is disconnected at the isolation structure. At least one of the light-emitting functional layers is disconnected at the isolation structure, so that the probability of crosstalk between the adjacent sub-pixels is reduced.
