The present disclosure provides a display panel and a display device. The display panel includes a substrate, and a driving circuit layer disposed at a side of the substrate. The driving circuit layer includes multistage gate driving units disposed in a non-display area and stage transmission signal lines connecting the gate driving units of different stages. The driving circuit layer includes a first semiconductor layer disposed at the side of the substrate, the first semiconductor layer includes a plurality of first semiconductors disposed in non-display regions, and the gate driving units include the first semiconductors; and the stage transmission signal line is disposed between the first semiconductor layer and the substrate, and is arranged to overlap with at least a portion of the gate driving unit in the non-display area.
