This disclosure relates to an organic electroluminescent structure, a fabrication method thereof, and a display device. The organic electroluminescent structure includes a base substrate; a passivation protective layer formed at a side of the base substrate, in which the passivation protective layer is formed with a plurality of inner cutting portions arranged at intervals at a side facing away from the base substrate; an anode layer including a plurality of anodes arranged at intervals, and each of the anodes is correspondingly formed on the second surface; an organic light-emitting functional layer having a hole injection layer, in which the hole injection layer includes a plurality of hole injection blocks arranged at intervals, and each of the hole injection blocks is correspondingly formed on one anode; and a cathode layer formed at a side of the organic light-emitting functional layer facing away from the anode layer.
