Abstract

The display substrate may include a base substrate, a plurality of sub-pixels in an array on the base substrate, an isolation layer on a side of a second electrode layer opposite from the light-emitting layer, and an auxiliary conductive layer on a side of the isolation layer opposite from the second electrode layer. The isolation layer may comprise via openings, orthographic projection of each of the via openings on the base substrate may substantially overlap with orthographic projection of the pixel defining layer on the base substrate, and the auxiliary conductive layer may be connected to the second electrode layer through the via openings.
