Abstract
A display substrate, comprising: a plurality of first electrodes having a planar middle part which are located on a planarization layer of a driving backplane, a spacing groove exposing a planar surface of the planarization layer being provided between two adjacent first electrodes; an electric leakage blocking layer located on a first electrode layer and located between two adjacent first electrodes, the electric leakage blocking layer being provided with a blocking groove corresponding to the spacing groove and exposing the planar surface of the planarization layer, and the electric leakage blocking layer being overlapped on the surface of the middle part on at least one side; and a light-emitting functional layer located at the side of the electric leakage blocking layer and the first electrode layer away from the driving backplane.
