Abstract: Provided are a display panel and a display apparatus. The display panel includes a substrate, a drive layer, and a pixel layer. The pixel layer is located at a side of the drive layer away from the substrate. The drive layer includes a first metal layer that is a metal layer that is closer to the pixel layer in the drive layer. The first metal layer includes data lines and a first signal line that extend in a same direction. The first signal line transmits a constant voltage signal. The pixel layer includes a plurality of sub-pixels, and each sub-pixel includes a light-emitting region. The light-emitting region is located between adjacent data lines. The first signal line overlaps with centers of the light-emitting regions of some of the sub-pixels.

Abstract: A display panel and a display device are provided. The display panel includes pixels and first signal lines electrically connected to the pixels, wirings, and a shielding part. The pixels, the first signal lines, and at least part of one wiring are located in a display region. The wirings include first and second wirings, one first wiring is electrically connected to one first signal line, and the second wiring is insulated from the first wiring, one second wiring has a fracture end located in the display region, and one first wiring is located on a side of the fracture end away from one of the at least one second wiring. In a direction perpendicular to a plane of the display panel, the shielding part is located at a side of the wirings close to a light-exiting side of the display panel, and the shielding part overlaps with the fracture end.
