Document Type and Number:
WIPO Patent Application WO/2023/173313
Kind Code:
A1
Abstract:
The present disclosure provides a display substrate and a manufacturing method therefor, and a display apparatus. The display substrate comprises: a base structure, which comprises a base substrate; and a light-emitting structure, a pixel defining layer and a connecting structure, wherein at least part of the light-emitting structure is located in an opening of the pixel defining layer; the connecting structure is located on the side of the pixel defining layer that is away from the opening; the light-emitting structure comprises a conductive structural layer, a first light-emitting layer and a first electrode layer, part of the first electrode layer and part of the first light-emitting layer being located on the side face of the pixel defining layer that is close to the connecting structure, and the first electrode layer being electrically connected to the connecting structure; and the connecting structure comprises a first conducting layer, a second conducting layer and a top structure, an orthographic projection of the second conducting layer on the base substrate being located within an orthographic projection of the top structure on the base substrate, the top structure comprising a second light-emitting layer, and an orthographic projection of the first light-emitting layer on the base substrate partially overlapping with an orthographic projection of the second light-emitting layer on the base substrate.
