Claim Text:
1. A touch display, comprising: a display module having a polarizer disposed at top thereof; and a touch module disposed above the display module, the touch module including a first three-layer electrode structure and a transparent cover substrate, the first three-layer electrode structure being disposed above the polarizer, and the transparent cover substrate being disposed above the first three-layer electrode structure; wherein the first three-layer electrode structure includes a bottom index matching layer, a mesh electrode layer and a top index matching layer, the mesh electrode layer being sandwiched between the bottom index matching layer and the top index matching layer; wherein the bottom index matching layer and the top index matching layer of the first three-layer electrode structure have refractive indices distinct from a refractive index of an externally neighboring layer, such that a light deviated from a normal line caused by the externally neighboring layer is therefore be reversed back to the normal line, thereby enhancing light transmittance.
