Abstract

A display substrate, a display panel, and a display device. The display substrate comprises sub-pixels, a pixel defining layer, a first defining structure, and a support structure; the pixel defining layer comprises a plurality of openings and a pixel defining portion; the plurality of openings comprise a plurality of first openings and a plurality of second openings; the first defining structure comprises a first portion overlapping with the pixel defining portion and a second portion exposed out of the second openings; the second portion of the first defining structure is configured to isolate at least one layer in a light-emitting function layer; the minimum distance between the orthographic projection of the support structure on a base substrate and the orthographic projection of the first defining structure on the base substrate is a first distance; the minimum distance to the orthographic projection of the second openings on the base substrate is a second distance; and the first distance and the second distance are both greater than 0 micrometer and less than 10 micrometers. Therefore, the support structure has a good shape and provides reliable support force while the light-emitting function layer is isolated to reduce crosstalk.
