摘要： Provided are a display panel and a display device. An isolation dam is provided in a peripheral area of the display panel. The display panel includes: a display functional layer comprising a plurality of display signal traces; and a touch-control functional layer comprising a plurality of touch-control signal traces. On the binding side, there are a first boundary and a second boundary, and a first trace area located between the first boundary and the second boundary, the first boundary is closer to the display area than the second boundary. In the first trace area, the touch-control signal trace is arranged along a first direction and are led out from the binding circuit and connected to the touch-control pattern via the isolation dam and the first trace area in sequence, the display signal trace is arranged along a second direction and intersects with the touch signal trace. The display panel further comprises a signal shielding layer between the touch-control signal traces and the display signal traces in a direction perpendicular to the substrate, and an orthographic projection of the signal shielding layer onto the substrate at least partially covers the intersection area of the touch-control signal trace and the display signal trace within the first trace area. The display panel and display device can improve operational stability and reliability.
