Abstract

A touch structure, a touch display panel and an electronic apparatus are provided. The touch structure includes a first touch electrode extended along a first direction and a second touch electrode extended along a second direction; the first touch electrode includes first electrode main body portions in a first conductive layer and a first connection portion in a second conductive layer; the second touch electrode includes second electrode main body portions and a second connection portion in the first conductive layer; the first connection portion is overlapped with the second connection portion in a direction perpendicular to the first conductive layer; the first conductive layer includes first metal meshes formed by first metal lines. The touch structure also includes a dummy electrode in the second conductive layer. The dummy electrode is coupled with at least one of the first connection portion and the second connection portion.
