Abstract

A display panel and a display device are provided. The display panel includes a display region; a non-display region; and at least one notch. The display region includes a first edge, a plurality of data lines, a plurality of scanning lines, and a plurality of light-emitting control lines. The plurality of data lines and the first edge extend along a column direction. The first edge is recessed toward the display region to form the at least one notch. The plurality of light-emitting control lines includes first light-emitting control lines and second light-emitting control lines. The non-display region includes a plurality of first light-emitting controllers in a cascade configuration disposed at one side of the first light-emitting control lines away from the at least one notch. An output terminal of each of the plurality of first light-emitting controllers is electrically connected to at least one of the first light-emitting control lines.
