Title:
DISPLAY SUBSTRATE AND MANUFACTURING METHOD THEREFOR, AND DISPLAY DEVICE
Document Type and Number:
WIPO Patent Application WO/2024/044964
Kind Code:
A1
Abstract:
A display substrate and a manufacturing method therefor, and a display device. The display substrate comprises a base substrate and a plurality of sub-pixels. Each sub-pixel comprises a light-emitting element, the light-emitting element comprises a light-emitting functional layer, a first electrode, and a second electrode, and the first electrode is located between the light-emitting functional layer and the base substrate. The display substrate further comprises define structures, the first orthographic projection of the surface of the side, close to the base substrate, of a define structure located between adjacent sub-pixels on the base substrate is completely located in the second orthographic projection of the surface of the side, away from the base substrate, of the define structure on the base substrate, the maximum size of the second orthographic projection is larger than the maximum size of the first orthographic projection, and the define structure comprises an inorganic non-metal material; at least one light-emitting functional layer is disconnected at the edge of the define structure, and the second electrodes of adjacent sub-pixels are at least partially continuously arranged. The problem of brightness uniformity can be avoided while crosstalk generated between adjacent sub-pixels is reduced.
