Document Type and Number:
WIPO Patent Application WO/2021/063390
Kind Code:
A1
Abstract:
A display substrate provided with a plurality of pixel areas. The display substrate comprises a base, a storage groove layer arranged on the base, an electrical connection structure arranged on the base, and a light-emitting layer arranged in each storage groove. A contact hole and a plurality of storage grooves are formed in the storage groove layer. The plurality of storage grooves are located at the periphery of the contact hole. Each storage groove and the contact hole are arranged at an interval. The plurality of storage grooves and the contact hole penetrate through the storage groove layer in the direction perpendicular to the base. Part of the electrical connection structure passes through the contact hole. From among position points on the boundary of the orthographic projection of the contact hole on the base, the position point, with the distance from same to a wall face of at least one storage groove in the periphery of the contact hole being the minimum, is a first position point. The orthographic projections of the contact hole and the plurality of storage grooves on the base are polygons or approximate polygons, the first position points are not located at the corners of the polygons or approximate polygons, and the edge, closest to the storage grooves, of the contact hole is not parallel to the edges, close to the contact hole, of the storage grooves.
