## Abstract

A layout method of a touch panel electrode includes the steps of: providing a substrate; forming a first electro-conductive layer, having pattern blocks disposed adjacently to one another, on one side of the substrate, wherein the first electro-conductive layer is transparent; forming an alignment film on the one side of the substrate; forming an second electro-conductive layer, having wires to be connected to at least one of the pattern blocks, on the one side of the substrate; and forming a protection layer on the second electro-conductive layer to protect the second electro-conductive layer. The present invention can reduce the processes of manufacturing the conventional electrode, especially do not needs to form another electro-conductive layer and another protection layer on the other side of the substrate, and can effectively prevent the electrostatic charge effect and increase the capacitance and sensitivity.
