Display panel, manufacturing method therefor, and display apparatus

A display panel, comprising:

• a base substrate;
• a padding layer, wherein the padding layer is disposed on a side of the base substrate;
• a thin film transistor structure layer, wherein the thin film transistor structure layer is disposed on a side of the base substrate;
• a planarization layer, wherein the planarization layer is disposed on a side of the thin film transistor structure layer away from the base substrate;
• an organic electroluminescent device, wherein the organic electroluminescent device is disposed on a side of the planarization layer away from the base substrate, and the organic electroluminescent device comprises an anode, an effective emitting layer, and a cathode that are stacked;
• an auxiliary electrode, wherein the auxiliary electrode is disposed on a side of the padding layer away from the base substrate, and an orthographic projection of the auxiliary electrode on the base substrate has an overlapping region with an orthographic projection of the padding layer on the base substrate, and is not overlapped with an orthographic projection of the effective emitting layer on the base substrate;
• and
• an ineffective emitting layer, wherein the ineffective emitting layer is disposed on a surface of the auxiliary cathode away from the base substrate, and there is a gap between an outer edge of the ineffective emitting layer and the effective emitting layer.
