Abstract

A transparent conductive gas barrier laminate according to the present disclosure includes a transparent gas barrier film and a transparent conductive layer in this order from outside toward inside. In the laminate, the transparent gas barrier film has a b* value of more than 0 in a L*a*b* color system, and the transparent conductive layer contains a conductive polymer and has a b* value of less than 0 in the L*a*b* color system.

First claim

What is claimed is:

1 . A transparent conductive gas barrier laminate, comprising:
a transparent gas barrier film and a transparent conductive layer in this order from outside toward inside, wherein the transparent gas barrier film has a b* value of more than 0 in a L*a*b* color system; and the transparent conductive layer contains a conductive polymer and has a b* value of less than 0 in the L*a*b* color system.

2 . A transparent conductive gas barrier laminate, comprising:
a transparent gas barrier film and a transparent conductive layer in this order from outside toward inside, wherein the transparent gas barrier film has a b* value of more than 0 in a L*a*b* color system; the transparent conductive layer contains a mixture of polyethylene dioxythiophene and polystyrene sulfonic acid; and the laminate has a b* value of less than 0 in the L*a*b* color system.

3 . The transparent conductive gas barrier laminate of claim 1 , wherein the transparent gas barrier film has ultraviolet shielding properties.

4 . The transparent conductive gas barrier laminate of claim 1 , wherein
the transparent gas barrier film includes a transparent base film and a barrier layer that is formed on at least one surface of the transparent base film; and the barrier layer at least includes a silicon oxide-deposited layer.

5 . The transparent conductive gas barrier laminate of claim 1 , wherein
the transparent gas barrier film includes at least two pairs of films, each pair being a transparent base film and a barrier layer that is formed on at least one surface of the transparent base film, and further includes an adhesive layer interposed between the two pairs; and the barrier layer at least includes a silicon oxide-deposited layer.

6 . The transparent conductive gas barrier laminate of claim 4 , wherein the transparent base film has ultraviolet shielding properties.

7 . The transparent conductive gas barrier laminate of claim 5 , wherein the adhesive layer has ultraviolet shielding properties.

8 . The transparent conductive gas barrier laminate of claim 1 , the laminate further comprising a transparent resin film having ultraviolet shielding properties and located on the outside of the transparent conductive layer.

9 . The transparent conductive gas barrier laminate of claim 8 , wherein an adhesive layer is interposed between the transparent resin film having ultraviolet shielding properties and a film located adjacent to the transparent resin film.

10 . The transparent conductive gas barrier laminate of claim 1 , the laminate further comprising a coating layer on the outermost side thereof.

11 . The transparent conductive gas barrier laminate of claim 10 , wherein the coating layer has a pencil hardness of 2H or more.

12 . The transparent conductive gas barrier laminate of claim 1 , wherein the transparent conductive layer has a sheet resistance in a range of 100Ω/□ to 1,000 Ω/□.

13 . A device, comprising:
the transparent conductive gas barrier laminate of claim 1 , and a driven unit that is disposed so as to face the transparent conductive layer of the transparent conductive gas barrier laminate.
