Abstract
A display panel and a display device are provided. The display panel includes a base substrate, a transistor layer, a planarization layer, and a light-emitting device layer. The light-emitting device layer includes: anodes; a pixel definition layer defining opening regions and non-opening regions, and part of each anode being exposed in a respective opening region; light-emitting layers corresponding to the opening regions; and cathodes located at a side of the pixel definition layer and the light-emitting layers facing away from the base substrate. The display panel further includes a first auxiliary-pad layer located at a side of planarization layer facing the base substrate, in a direction perpendicular to a plane of the base substrate, each first auxiliary-pad layer does not overlap with each opening region and extends along an extension direction of at least part of an edge of a respective opening region.
