Abstract

A display panel and a display device are provided. The display panel has a display region and a peripheral region surrounding the display region. The display panel includes: a scan driving circuit arranged in the peripheral region; a low-level voltage signal line arranged in the peripheral region and electrically connected to the scan driving circuit; an auxiliary metal line arranged in the peripheral region and electrically connected to the low-level voltage signal line. The peripheral region includes a first and second peripheral region located on opposite sides of the display region in a first direction, and a third and fourth peripheral region located on opposite sides of the display region in a second direction, the first direction being perpendicular to the second direction. The auxiliary metal line at least extends in the first, third and second peripheral region to form a structure partially surrounding the display region.
