Abstract
A method of manufacturing a touch panel including providing a substrate having a display area and a peripheral area is provided. A metal layer and a metal nanowire layer are disposed, wherein a first portion of the metal nanowire layer is disposed in the display area, and a second portion of the metal nanowire layer and the metal layer are disposed in the peripheral area. A patterned layer with a pattern is disposed. A patterning step is performed according to the patterned layer, wherein the patterning step includes forming the metal layer into multiple peripheral wires and simultaneously forming the second portion of the metal nanowire layer into multiple etching layers by using an etching solution configured to etch the metal layer and the metal nanowire layer. A touch panel is further provided.
