Title:
TRANSPARENT CONDUCTIVE LAMINATED BODY AND TOUCH PANEL USING THE SAME
Document Type and Number:
Japanese Patent JP2002316378
Kind Code:
A
Abstract:

To provide a transparent conductive laminated body improved in its transparency and scratch resistance and flex resistance of the conductive thin film and improved in a pen input durability as a touch panel use in the transparent conductive thin film using a film substrate.

The transparent conductive laminated body is provided wherein a transparent first dielectric thin film, a transparent second dielectric thin film and a transparent conductive thin film are laminated in this order on one side surface of a transparent film substrate of 2-120 μm in thickness, and a transparent substrate is stuck to the other surface of the film substrate via a transparent pressure sensitive adhesive layer. When a refractivity of light of the film substrate is n1, a refractivity of light of the first dielectric thin film is n1, a refractivity of light of the second dielectric thin film is n3 and a refractivity of light of the electrical conductive thin film is n4, the transparent conductive laminated body satisfies a relation of n3<n2≤n1<n4.
