Abstract: Discussed is a method for manufacturing a touch device, the method including forming a protective layer per touch sensor on first and second surfaces of a mother substrate on which two or more touch sensors are formed; dividing the mother substrate into two or more substrates of a touch sensor unit by mechanically cutting or chemically treating the mother substrate; chemically strengthening an edge of each of the divided substrates; and removing the protective layer from at least one divided substrate.

Abstract: A touch device, a method for manufacturing a touch device and a resin composition used in the method are discussed. The touch device includes a substrate including a surface roughness of less than 1.2 nm, a touch sensor formed on a surface of the substrate, and a flexible printed circuit board attached to the substrate.
