Abstract
The present application provides a display panel and a display device. The display panel includes a display area and a fan-out area. The display panel further includes a substrate, a display layer including a common electrode trace, and a touch layer including a peripheral touch trace. In the fan-out area, a projection of the common electrode trace on the substrate and a projection of the peripheral touch trace on the substrate are at least partially overlapped, and at least three insulation film layers are provided between the common electrode trace and the peripheral touch trace in at least an area where their projections are overlapped.
