Abstract

A display substrate and a manufacturing method and a display device are provided. The display substrate includes: a first electrode pattern, a connecting electrode pattern, a second electrode, and a light-emitting functional layer. The first electrode pattern is located in a display region and includes a plurality of first electrodes spaced apart from each other. The connecting electrode pattern is located in a peripheral region and includes a plurality of connecting electrodes. The second electrode is connected with the connecting electrode pattern, the second electrode and the first electrode pattern being spaced apart from each other. The light-emitting functional layer is located between the first electrode pattern and the second electrode, the connecting electrode pattern surrounds the first electrode pattern, and at least two of the plurality of connecting electrodes are each of a block shape and are spaced apart from each other.
