Abstract:
The transparent conductive laminate of the present invention is a transparent conductive laminate, comprising: a transparent film substrate; a transparent conductive thin film provided on one side of the transparent film substrate with a dielectric thin film interposed therebetween; and a transparent substrate bonded to another side of the transparent film substrate with a transparent pressure-sensitive adhesive layer interposed therebetween, wherein the transparent substrate comprises at least two transparent base films laminated with the transparent pressure-sensitive adhesive layer interposed therebetween, and the dielectric thin film comprises a first transparent dielectric thin film consisting of a SiOx (x is from 1.5 to less than 2) film having a relative refractive index of 1.6 to 1.9, and a second transparent dielectric thin film consisting of a SiO2 film. This feature can improve the surface contact pressure durability.
