Claim 0:
1. A display panel, comprising:
a substrate; and
a conductive pattern, a light-emitting layer and a cathode layer which are laminated on the substrate in a direction that is perpendicular to and away from the substrate,
wherein the conductive pattern is formed by a one-time patterning process, and the conductive pattern comprises an auxiliary electrode layer, the auxiliary electrode layer comprising a first protective electrode, a metal electrode and a second protective electrode which are laminated in the direction that is perpendicular to and away from the substrate, wherein the first protective electrode and the second protective electrode both extend over the metal electrode in a direction parallel to the substrate, a second orthographic projection of the second protective electrode on the substrate is within a first orthographic projection of the first protective electrode on the substrate, and an outer boundary of the second orthographic projection is staggered from an outer boundary of the first orthographic projection; and
the cathode layer is in contact with the first protective electrode and a sidewall of the metal electrode;
wherein the conductive pattern further comprises an anode layer, the anode layer comprising a first sub-anode, a second sub-anode and a third sub-anode which are sequentially laminated in a direction away from the substrate; and
wherein a third orthographic projection of the third sub-anode on the substrate is within a fourth orthographic projection of the second sub-anode on the substrate, and an outer boundary of the third orthographic projection is staggered from an outer boundary of the fourth orthographic projection.
