NARROW FRAME TOUCH INPUT SHEET WITH PROTECTION FILM, LAMINATE NARROW FRAME TOUCH INPUT SHEET WITH PROTECTION FILM AND METHOD FOR MANUFACTURING THEM

摘要

PROBLEM TO BE SOLVED: To provide a narrow frame touch input sheet with a protection film and a laminate narrow frame touch input sheet with a protection film which are suitable for a capacitance type touch sensor with a narrow frame and a two-layered transparent conductive film pattern and a method for manufacturing them.;SOLUTION: A transparent conductive film, a light shielding conductive film for electrode, and a first resist layer are successively formed on the both faces of a base sheet, and the first resist layer is simultaneously exposed and developed on the both faces, and the transparent conducive film and the light shielding conductive film for an electrode are simultaneously etched, and the first resist layer is peeled, so that a thin wire leading circuit pattern in which the transparent conductive film and the light shielding conductive film for an electrode are laminated can be formed at the external frame sections of the both faces of the base sheet, and after that the both face thin wire leading circuit pattern is coated with a second resist layer, and only the light shielding conductive film for an electrode on which the second resist layer is not formed is etched so that the circuit pattern of the transparent conductive film can be formed, so as to be exposed at each of the both face central window portions, and the light transmitting protection film is laminated.;COPYRIGHT: (C)2011,JPO&INPIT
