Abstract

Disclosed is an input device comprising: an input member which is provided with a pair of conductive substrates including an insulating substrate and a transparent conductive film (12,22) which is provided on the insulating substrate and has a net-like member made of conductive metal in an insulating transparent substrate (2) such that the pair of conductive substrates is laminated in the thickness direction; and a detection means which is electrically connected to the transparent conductive film (12, 22) and detects an input signal; wherein the transparent conductive film (12, 22) is provided with a conductive part which is formed with the net-like member arranged in the transparent substrate (2); and an insulating part (I) which is formed by removing at least a part of the net-like member in the transparent substrate (2).

Description

technical field [0001] The present invention relates to an input device provided in front of an image display device such as a touch panel or an electromagnetic wave shield of a plasma display. Background technique [0002] In a touch panel, an input device is provided as an electrode sheet on the front of an image display device such as a liquid crystal display. The input device has a conductive layer (transparent conductive film) formed on the surface of a transparent insulating substrate. substrate. [0003] As a material for the transparent conductive layer constituting the conductive substrate of the input device, there are known π-copolymers such as indium tin oxide (ITO) or polyethylenedioxythiophene-polyethylenesulfonic acid Conjugated conductive polymers (organic conductors). [0004] In addition, a circuit pattern or an antenna array pattern is formed on the conductive substrate used in the touch panel input device. [0005] As a pattern forming method, for exam...
