Title:
DISPLAY SUBSTRATE AND DISPLAY APPARATUS
Document Type and Number:
WIPO Patent Application WO/2023/245614
Kind Code:
A1
Abstract:
Provided are a display substrate and a display apparatus. The display substrate comprises a plurality of sub-pixels, which are arranged in an array on a base substrate in a first arrangement direction and a second arrangement direction, wherein the plurality of sub-pixels comprise a plurality of light-emitting areas; a first electrode layer, which is located on the base substrate, wherein the first electrode layer comprises a plurality of anode structures; and a pixel defining layer, which is located on the side of the first electrode layer that is away from the base substrate, wherein the pixel defining layer comprises a plurality of openings, so as to define the plurality of light-emitting areas. With regard to at least some of the plurality of sub-pixels, an orthographic projection of an opening of each sub-pixel on the base substrate falls within an orthographic projection of an anode structure of the sub-pixel on the base substrate, and the shape of a pattern of the orthographic projection of the opening of each sub-pixel on the base substrate is different from the shape of a pattern of the orthographic projection of the anode structure of the sub-pixel on the base substrate. The number of symmetrical axes of the pattern of the orthographic projection of the anode structure of each sub-pixel on the base substrate is greater than the number of symmetrical axes of the pattern of the orthographic projection of the opening of the sub-pixel on the base substrate.
