An organic electroluminescent display element includes a substrate, a plurality of first electrodes, an auxiliary electrode, an insulating layer, an organic layer, a second electrode, and a conductive material. The auxiliary electrode is provided between the plurality of first electrodes on the substrate and separated from the plurality of first electrodes. The insulating layer covers the auxiliary electrode, separates and isolates the plurality of first electrodes from each other, and has through holes extending to the auxiliary electrode. The organic layer is provided on each of the plurality of first electrodes. The second electrode covers a whole surface of the insulating layer and the organic layers and allowing light emitted in the organic layers to transmit therethrough. The conductive material is provided in the through holes, for electrically connecting the auxiliary electrode to the second electrode.
