PRODUCTION OF ELECTROMAGNETIC WAVE SHIELDING FILM AND ELECTROMAGNETIC WAVE SHIELDING BODY AND DISPLAY USING THE ELECTROMAGNETIC WAVE SHIELDING FILM

摘要

PROBLEM TO BE SOLVED: To provide an electromagnetic wave shielding film having electromagnetic wave shieldability, transparent and invisibility and an electromagnetic wave shielding body and display using the same. SOLUTION: The electromagnetic wave shielding film is produced by forming geometrical graphics with an etching resist by an intaglio offset printing method on the conductive metal of a plastic film with the conductive metal consisting of the conductive metal and a plastic base in such a manner that its aperture ratio attains >=50% and etching the conductive metal thereby forming the geometrical graphics drawn by the conductive metal. The electromagnetic wave shielding body is formed by laminating such electromagnetic wave shielding film and a transparent base material. Electromagnetic waves are shielded by using the electromagnetic wave shielding film or the electromagnetic wave shielding body as a display.
