Abstract
An electromagnetic wave shielding filter 10 comprises a transparent substrate 1, and a mesh layer 3 containing an electrically conductive layer 2, formed on the transparent substrate 1 with a transparent adhesive layer 9. A transparent colored resin layer 4 containing a coloring agent is formed on the mesh layer 3, with a transparent barrier layer 5 interposed between the two layers. An anticorrosive layer 6 and a blackening layer 7 are formed on the electrically conductive layer 2 in the mesh layer 3. The transparent colored resin layer 4 also serves as an adhesive layer, and a functional layer 8, such as an optical filter, a protective sheet, or a display front substrate, is further laminated to the transparent colored resin layer 4.
Claims11
An electromagnetic wave shielding filter comprising:
- a transparent substrate,
- a transparent adhesive layer made from a urethane adhesive, formed on the transparent substrate,
- a mesh layer in the form of a mesh, containing at least an electrically conductive layer made from a metal, formed on the transparent adhesive layer, and
- a transparent colored resin layer containing a coloring agent and an adhesive, formed on the mesh layer,
- a transparent barrier layer for separating the mesh layer and the transparent colored resin layer from each other, made from a non-urethane, non-adhesive solid resin, being present between the mesh layer and the transparent colored resin layer.
