Abstract: An array substrate includes gate lines, data lines and an insulating layer. The data lines all extend in a first direction, and the gate lines all extend in a second direction, the first direction intersecting the second direction. A data line includes first line segments and second line segments that all extend in the first direction and are arranged alternately. The second line segments are disposed at a side of the gate lines proximate to the base, and the first line segments are disposed at a side of the gate lines away from the base. There is no overlap among orthographic projections of the first line segments on the base and orthographic projections of the gate lines on the base. The insulating layer includes first vias. In the first direction, any two adjacent first line segments are electrically connected to a second fine segment through at least two first vias.

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.
