1. A display panel, comprising:
a backplane;
a first electrode and an auxiliary layer, disposed on a same side of the backplane, wherein a distance between a surface of the first electrode distal from the backplane and the backplane is shorter than or equal to a distance between a surface of the auxiliary layer distal from the backplane and the backplane;
a pixel defining layer, at least partially disposed on a side of the auxiliary layer distal from the backplane;
a second electrode, disposed on a side of the pixel defining layer distal from the backplane; and
an auxiliary electrode, disposed on a side of the second electrode distal from the backplane, wherein an orthographic projection of the auxiliary electrode onto the backplane is located within an orthographic projection of the pixel defining layer onto the backplane;
wherein the backplane comprises an insulation layer, and
the insulation layer comprises a groove and a protrusion, the first electrode is disposed within the groove, and a thickness of the first electrode is less than or equal to a depth of the groove;
the display panel further comprising:
a height-enhanced layer, disposed on a side of the protrusion distal from the backplane, wherein the height-enhanced layer and the protrusion are comprised in the auxiliary layer.
