Abstract: The present disclosure relates to an array substrate and a method for manufacturing the same. The array substrate includes a thin film transistor and comprises at least a first region and a second region. A thickness of an active layer of the thin film transistor in the first region is different from that of an active layer of the thin film transistor in the second region. A ratio of the overlapped area between the source electrode or the drain electrode and the active layer of the thin film transistor to the thickness of the active layer is kept uniform over the first region and the second region.

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.
