Touch structure and method of manufacturing the same, touch substrate and touch display device

A touch structure, comprising:

• a touch functional layer configured to identify a touch, wherein the touch functional layer includes a first conductive layer and a second conductive layer that are stacked, and the first conductive layer includes a plurality of electrodes spaced apart from each other;
• and
• a first transparent layer, wherein orthographic projections of the plurality of electrodes and a region between any two adjacent electrodes of the plurality of electrodes on a plane perpendicular to a thickness direction of the touch functional layer is within a range of an orthographic projection of the first transparent layer on the plane, wherein
• the first transparent layer is disposed at a side of the first conductive layer away from the second conductive layer, and a refractive index of the first transparent layer is greater than or equal to a refractive index of the first conductive layer, or
• the first transparent layer is disposed between the first conductive layer and the second conductive layer, a material of the first transparent layer is an insulating material, and the refractive index of the first transparent layer is equal to the refractive index of the first conductive layer.
