Title:
DISPLAY SUBSTRATE AND DISPLAY DEVICE
Document Type and Number:
WIPO Patent Application WO/2021/190508
Kind Code:
A1
Abstract:
A display substrate and a display device. The display substrate comprises a base substrate, and a pixel circuit layer comprising a plurality of pixel driving circuits, a first conductive layer, a first planarization layer and a second conductive layer; the second conductive layer comprises a plurality of conductive portions, the plurality of conductive portions include a first conductive portion, the first conductive portion comprises a closed annular portion, and the closed annular portion and at least one conductive portion adjacent in a first direction are separated from each other on the second conductive layer; each light emitting element group comprises a first light emitting element, and the first light emitting element comprises a first anode; the orthographic projection of the first anode on the base substrate overlaps the orthographic projection of the closed annular portion on the base substrate; and the plurality of conductive portions further include a second conductive portion adjacent to the first conductive portion, and the orthographic projection of the second conductive portion on the base substrate overlaps with the orthographic projection of the first anode on the base substrate. Thus, the display substrate can effectively reduce the color shift.
