    Abstract: A display panel includes: a substrate; at least one first signal line disposed on the substrate and located in a peripheral region; at least one second signal line disposed on the substrate and located in the peripheral region; an insulating layer covering the at least one first signal line and the at least one second signal line; and a shielding signal line covering the at least one groove. The at least one second signal line and the at least one first signal line are arranged in a same layer. A surface of the insulating layer away from the substrate has at least one groove. An orthogonal projection, on the substrate, of a bottom surface of a groove is located between orthogonal projections, on the substrate, of a first signal line and a second signal line.
