Display panel and display device

A display panel, comprising:

• a substrate, comprising a display area and a non-display area that surrounds the display area;
• a first metal layer, disposed on the substrate and located in the non-display area;
• a first insulating layer, disposed on the first metal layer and the substrate;
• a second metal layer, disposed on the first insulating layer and located in the non-display area;
• a second insulating layer, disposed on the second metal layer and the first insulating layer and covering the first metal layer and the second metal layer;
• a sealant, disposed on the second insulating layer;
• a plurality of first driving circuits, configured to drive scan lines arranged in the display area;
• and
• a plurality of second driving circuits, configured to drive data lines arranged in the display area;
• wherein the first metal layer and the second metal layer are arranged in a same orientation, and are configured to couple together two adjacent first driving circuits or two adjacent second driving circuits, wherein the first metal layer comprises a plurality of first metal lines, the second metal layer comprises a plurality of second metal lines, wherein projections of the first metal line and the second metal line that are arranged in a same orientation along a direction perpendicular to the substrate do not overlap, and projections of every two adjacent first metal line and second metal line that are arranged in the same orientation along the direction perpendicular to the substrate are positioned at equal intervals, and wherein a projection of the sealant along the direction perpendicular to the substrate at least partially overlaps the projections of the first metal lines and the second metal lines along the direction perpendicular to the substrate;
• the plurality of first metal lines comprises a plurality of first metal first lines and a plurality of first metal second lines, the plurality of second metal lines comprises a plurality of second metal first lines and a plurality of second metal second lines, wherein the plurality of first metal first lines are arranged in a same orientation as the plurality of second metal first lines, the plurality of first metal second lines are arranged in a same orientation as the plurality of second metal second lines, and the plurality of first metal first lines are not arranged in the same orientation as the plurality of first metal second lines;
• wherein the projections of the plurality of first metal first lines along the direction perpendicular to the substrate do not overlap the projections of the plurality of second metal first lines along the direction perpendicular to the substrate, the projections of the plurality of first metal second lines along the direction perpendicular to the substrate do not overlap the projections of the plurality of second metal second lines along the direction perpendicular to the substrate, the plurality of first metal first lines are arranged perpendicular to the plurality of first metal second lines seen from the direction perpendicular to the substrate, and the plurality of second metal first lines are arranged perpendicular to the plurality of second metal second lines seen from the direction perpendicular to the substrate;
• wherein an upper surface of at least a part of the second insulating layer located on the first metal layer has a same height as that of an upper surface of at least a part of the second insulating layer located on the second metal layer.
