Patent ID: 7086146

Claim:
A shielding base member manufacturing method comprising the steps of: forming a metal foil on a plastic film, serving as a support, via a resin layer enhancing the rigidity of the plastic film, a first adhesive layer, and a release layer on a surface of the plastic film, to provide a first structure including, in sequence, the plastic film, the release layer, the first adhesive layer in direct contact with a surface of the release layer at an interface therebetween, the resin layer and the metal foil; forming metal layer patterns by etching the metal foil with roll-to-roll processing, the resin layer protecting the first adhesive layer from contact with etchant during etching; separating the plastic film and the release layer from the first adhesive layer along said interface; and then pasting the first adhesive layer onto a transparent substrate to provide a second structure including, in sequence, the transparent substrate, the first adhesive layer, the resin layer and the metal layer patterns.
