Abstract

A display substrate and a display device. The display substrate comprises sub-pixels, pixel defining patterns, and defining structures. The sub-pixels each comprise a light-emitting functional layer; the pixel defining patterns each comprise openings and pixel defining portions surrounding the openings, and at least part of each light-emitting functional layer is isolated in at least one opening; and the defining structures are located between the pixel defining portions and a base substrate. The defining structures each are located between two corresponding adjacent sub-pixels of different colors; the defining structures each comprise a first portion covered by the corresponding pixel defining portion and a second portion exposed out of the corresponding opening; the second portions of the defining structures are configured to isolate the light-emitting functional layers; and the defining structures are made of an organic material, and the orthographic projection of the edge of the side surface of each second portion distant from one side of the base substrate on the base substrate falls within the orthographic projection of the corresponding opening on the base substrate, such that the corresponding light-emitting functional layer is isolated to reduce crosstalk, thereby minimizing the effect of the defining structures on the process and productivity while guaranteeing the electrode flatness and normal light-emitting effects of the sub-pixels.
