1. A touch structure, comprising 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,
wherein, in a plane parallel to the surface of the substrate, a line width of each second portion of the plurality of the second metal lines is greater than a line width of each first portion of the plurality of the first metal lines; and
orthographic projections of the first portions of the plurality of the first metal lines on the substrate are within orthographic projections the second portions of the plurality of the second metal lines on the substrate.
