Abstract: A display substrate and a method of manufacturing the display substrate are provided. The display substrate includes a base substrate and a plurality of sub-pixels (Pxl). A first electrode of a light-emitting element of the sub-pixel (Pxl) includes: a first conductive layer electrically connected to a source (S) or a drain (D) of a driving transistor of the sub-pixel (Pxl); a second conductive layer; and a transparent material layer. The transparent material layer includes a first transparent material sub-layer and a second transparent material sub-layer, the first transparent material sub-layer is between the second transparent material sub-layer and the second conductive layer, the second transparent material sub-layer covers the first transparent material sub-layer, and an edge of the first transparent material sub-layer is aligned with an edge of the second conductive layer.
