Abstract

A display panel, a method for manufacturing the same, a display device and a method for manufacturing the same are provided. The display panel includes a display region and a peripheral region arranged on a substrate, and further includes multiple active driving circuits and multiple redundant driving circuits. At least one active driving circuit is electrically connected to at least one of multiple pixel units, and each redundant driving circuit includes at least one electrode layer arranged on the substrate. The peripheral region includes a flat region and a curved region, at least part of the redundant driving circuits are located in a flat redundant driving circuit region included in the flat region. The flat redundant driving circuit region includes at least two alignment mark regions. In the alignment mark regions, at least one electrode layer is hollowed out, and/or at least one electrode layer is filled up.
