Title:
DISPLAY SUBSTRATE AND MANUFACTURING METHOD THEREFOR, AND DISPLAY APPARATUS
Document Type and Number:
WIPO Patent Application WO/2023/097529
Kind Code:
A1
Abstract:
A display substrate and a manufacturing method therefor, and a display apparatus. The display substrate comprises a base substrate, and a plurality of sub-pixels located on the base substrate, wherein each sub-pixel comprises a light-emitting functional layer. A defining structure is arranged between adjacent sub-pixels, and the defining structure comprises a first sub-structure and a second sub-structure which are arranged in a stacked manner; in the arrangement direction of the adjacent sub-pixels, an edge of the second sub-structure protrudes relative to an edge of the first sub-structure, so as to form a protruding portion, or a side surface of the second sub-structure is provided with a first slope angle, and a side surface of the first sub-structure is provided with a second slope angle, wherein at least one of the first slope angle and the second slope angle is greater than 60 degrees; and at least one of a plurality of film layers comprised in the light-emitting functional layer is disconnected at the defining structure. The defining structure in the display substrate can enable at least one layer of the light-emitting functional layer to be disconnected at the defining structure, thereby facilitating the reduction of the probability of crosstalk between adjacent sub-pixels.
