Document Type and Number:
WIPO Patent Application WO/2011/148979
Kind Code:
A1
Abstract:
Disclosed is an electromagnetic shielding filter which is capable of enhancing electromagnetic shielding performance, transmittance and flame retardancy, while being reduced in weight.
Specifically disclosed is an electromagnetic shielding filter which is obtained by sequentially laminating in the following order: an optical function layer (1) that has a thickness of 0.01-20 μm and an anti-reflection function or an anti-glare function; a transparent resin film (2) that has a thickness of 25-100 μm; a first transparent layer (3) that has a thickness of 1-75 μm; a conductor pattern layer (4) that is composed of a grid-like conductor pattern having a thickness of 0.1-100 μm, a conductor width of 5-50 μm and a conductor pitch of 50-800 μm; a second transparent layer (5) that has a thickness of 1-100 μm; and a chemically strengthened glass material (6) that has a thickness of 0.5-2.5 mm or a double glass material (7) that has a thickness of 0.2-2.5 mm.
