The present application provides a display panel and a display device. The display panel comprises: a base substrate; an insulating layer arranged on the base substrate, the insulating layer being provided with recesses spaced from each other; metal lines arranged on one side of the insulating layer away from the base substrate, portions of the metal lines corresponding to the recesses being located in the recesses, the metal lines having a corrugated longitudinal cross-section in an extending direction of the metal lines to reduce a risk of the metal lines breaking during bending and improve flexibility of the display panel.
