Display panel, method for manufacturing the display panel, and display device

A display device, comprising a display panel, wherein the display panel comprises:

• a substrate having a top side and a bottom side;
• a plurality of first electrodes and an auxiliary electrode disposed on the top side of the substrate;
• a plurality of light-emitting elements, which are on a side, facing away from the substrate, of first electrodes and the auxiliary electrode, wherein a first pole of one of the plurality of light-emitting elements is connected to one of the plurality of first electrodes;
• a second electrode disposed on the plurality of light-emitting elements, wherein the second electrode is connected to a second pole of one of the plurality of light-emitting elements;
• and
• a conductive barrier disposed between two adjacent ones of the plurality of light-emitting elements, wherein the conductive barrier is electrically connected to the auxiliary electrode and the second electrode, wherein the conductive barrier comprises two sidewalls, wherein each of the two sidewalls comprises a reflective electrode, and wherein the reflective electrode reflects light emitted from an adjacent one of the plurality of light-emitting elements,
• wherein the auxiliary electrode comprises hollowed-out structures, and perpendicular projections of the plurality of light-emitting elements on the layer where the auxiliary electrode is located fall in the hollowed-out structures.
