Abstract

There is provided an electromagnetic wave shielding member comprising: a transparent film substrate; and a mesh formed of a thin metal film stacked on the surface of the transparent film substrate through an adhesive and/or a pressure-sensitive adhesive, the adhesive and/or the pressure-sensitive adhesive comprising an absorber which can absorb specific wavelengths, i.e., the wavelengths of visible light and/or near-infrared.

Claims

1. An electromagnetic wave shielding member comprising:

a transparent film substrate; and

a mesh formed of a thin metal film stacked on the surface of the transparent film substrate through an adhesive and/or a pressure-sensitive adhesive,

said adhesive and/or said pressure-sensitive adhesive comprising an absorber which can absorb specific wavelengths, i.e., the wavelengths of visible light and/or near-infrared.

2. The electromagnetic wave shielding member according to claim 1, which further comprises a layer, for flattening the concave/convex face of the mesh, stacked on the mesh layer formed of the thin metal film,

at least one of the adhesive and/or the pressure-sensitive adhesive and the flattening layer comprising an absorber which can absorb specific wavelengths, i.e., the wavelengths of visible light and/or near-infrared.

3. The electromagnetic wave shielding member according to claim 2, which further comprises a layer comprising an absorber, which can absorb specific wavelengths, i.e., the wavelengths of visible light and/or near-infrared, stacked on the surface of the transparent film substrate or the surface of the flattening layer.

4. The electromagnetic wave shielding member according to any one of claims 1 to 3, wherein the thin metal film is a thin film of copper.

5. The electromagnetic wave shielding member according to any one of claims 1 to 4, wherein the surface of the mesh formed of the thin metal film has been blackened.

6. The electromagnetic wave shielding member according to claim 5, wherein the blackening treatment has been made by chromate treatment.

7. An electromagnetic wave shielding member comprising:

the electromagnetic wave shielding member according to any one of claims 1 to 6; and

a visible light absorption layer and/or a near-infrared absorption layer stacked on the electromagnetic wave shielding member.

8. The electromagnetic wave shielding member according to claim 7, wherein an antireflection layer and/or an antiglare layer are further stacked.

9. The electromagnetic wave shielding member according to claim 7 or 8, wherein a transparent substrate is further stacked.

10. A display device comprising:

a display; and

the electromagnetic wave shielding member according to any one of claims 1 to 9 stacked on the surface of the display.
