Abstract: The present invention relates to a high-performance film-type touch sensor that has a low sheet resistance and can have a high resolution, a large area, and a small thickness, and a method of fabricating the same. In the high-performance film-type touch sensor which is peeled off from a substrate and to which a base film is bonded, at least a separation layer, an electrode pattern layer, and a protection layer are sequentially stacked on the base film, and one or more of first and second electrode patterns arranged in different directions on the separation layer are formed of a plurality of conductive layers to reduce sheet resistance.

Abstract: A touch screen panel is provided with electromagnetic wave shielding properties. The touch screen panel includes an electromagnetic wave shielding layer on a window substrate. The electromagnetic wave shielding layer may include at least one alloy selected from the group consisting of copper, iron, nickel, aluminum, tin, indium, zinc, gold and silver, and oxides thereof, as an electromagnetic wave shielding material. The electromagnetic wave shielding layer may include at least one electromagnetic wave shielding material selected from the group consisting of polypyrrole, polythiophene, and polyaniline. When the touch screen panel further includes an index matching layer, the electromagnetic wave shielding layer may be formed on at least one face of the index matching layer. When electromagnetic wave shielding material is included in the index matching layer, the index matching layer functions as the electromagnetic wave shielding layer.
