1. A display panel comprising a plurality of sub-pixel units, each of the plurality of sub-pixel units comprises:
a first metal layer, wherein the first metal layer comprises one longitudinal wire, and the first metal layer employs an axial symmetry structure;
a first planarization layer;
a first electrode layer, wherein the first electrode layer employs the axial symmetry structure;
a pixel definition layer, wherein the pixel definition layer employs the axial symmetry structure;
a light-emitting layer; and
a second electrode layer, wherein the second electrode layer employs the axial symmetry structure;
wherein the first metal layer, the first planarization layer, the first electrode layer, the pixel definition layer, the light-emitting layer and the second electrode layer are sequentially stacked; and
wherein the longitudinal wire is taken as a symmetry axis of the axial symmetry structure,
the first electrode layer of the sub-pixel unit comprises a protrusion, and the protrusion employs the axial symmetry structure.
