Touch structure, touch display panel, and display device

A touch display panel comprising a base substrate, and a display structure and a touch structure stacked on the base substrate, wherein the touch structure comprises:

• a substrate and a first metal grid electrode layer, an insulating layer, and a second metal grid electrode layer on the substrate, wherein the first metal grid electrode layer is located on a side of the second metal grid electrode layer away from the substrate, the insulating layer is disposed between the first metal grid electrode layer and the second metal grid electrode layer;
• the first metal grid electrode layer comprises a plurality of first metal grids formed by a plurality of first metal lines, the second metal grid electrode layer comprises a plurality of second metal grid formed by a plurality of second metal lines,
• first portions of the plurality of the first metal lines and second portions of the plurality of the second metal lines have same line extension directions, respectively, and overlap with each other in a direction perpendicular to a surface of the substrate, the insulating layer includes edge slope parts covering the second portions of the plurality of the second metal lines in a direction perpendicular to the line extension direction, each edge slope parts forms a step relative to the surface of the substrate, and the first portions of the plurality of the first metal lines at least partly do not overlap with the edge slope parts.
