Organic electroluminescent structure and fabrication method thereof, and display device

A fabrication method of an organic electroluminescent structure, comprising:

• forming a base substrate;
• forming a passivation protective layer and an anode layer at a side of the base substrate;
• in which a plurality of inner cutting portions arranged at intervals are formed at a side of the passivation protective layer away from the base substrate, each of the inner cutting portions has a first surface towards the base substrate and a second surface away from the base substrate, an orthographic projection of the first surface on the base substrate is within an orthographic projection of the second surface on the base substrate, and there is a non-zero distance between an edge of the first surface and an edge of the second surface;
• the anode layer comprises a plurality of anodes arranged at intervals, and each of the anodes is correspondingly formed on the second surface;
• forming an organic light-emitting functional layer with a hole injection layer on the base substrate, in which the hole injection layer comprises a plurality of hole injection blocks arranged at intervals, and each of the hole injection blocks is correspondingly formed on one of the anodes;
• and
• forming a cathode layer at a side of the organic light-emitting functional layer facing away from the anode layer.
