Abstract: A method for manufacturing a display panel includes: sequentially forming a conductive pattern, a light-emitting layer and a cathode layer on a substrate. The conductive pattern is formed by a one-time patterning process, and includes an auxiliary electrode layer. In a direction parallel to the substrate, both the first protective electrode and the second protective electrode in the auxiliary electrode layer extend over the metal electrode, 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. The cathode layer is in contact with the first protective electrode and a sidewall of the metal electrode.
