The display panel includes a substrate, a resistance reducing trace, an inter-layer-medium layer and a signal line. The substrate is divided into a plurality of sub-pixel regions and a pixel separating region. The resistance reducing trace is provided on the pixel separating region of the substrate. The inter-layer-medium layer is provided on the substrate, and the inter-layer-medium layer has an opening exposing the resistance reducing trace. The signal line is provided within the opening, the signal line is connected to the resistance reducing trace, the signal line is distributed in a column direction along the display panel, and in a row direction along the display panel, a width of the opening is greater than or equal to a width of the signal line.

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.
