Abstract:
A high performance touch sensor according to the present invention comprises: a substrate; a first detection electrode formed on the substrate; an insulation layer formed on the first detection electrode; a second detection electrode formed on the insulation layer; and a protection layer formed on the second detection electrode, wherein one of the first detection electrode and the second detection electrode has a triple-film structure including a metal oxide and a thin film metal laminated on each other, and the other one includes a metal pattern. Therefore, the present invention can implement touch sensor having a high resolution and a large area while simultaneously satisfying a low resistance characteristic and an optical characteristic, facilitate progress of a high-temperature process, and diversify the substrate.
