Abstract
Provided is an electromagnetic wave shielding mesh, which is arranged on the front face of a display such as a PDP (Plasma Display Panel) or an FED (Field Emission Display) thereby to shield the leakage of electromagnetic waves. The electromagnetic wave shielding mesh has excellent light transmitting and electromagnetic wave shielding properties, but has neither moire nor brightness mottle in a manner to match the display having various pixel pitches. The electromagnetic wave shielding mesh is characterized in that it is woven of fibrous filaments and has a metallic cover film formed on its surface to give an electric conductivity, and in that its ratio (R) of a weft density to a warp density is 0.67≦R≦0.97, or 1.03≦R≦1.50.
Claims8
An electromagnetic wave-shielding mesh woven with fiber yarns and coated an electrically conductive metal onto each yarn, characterized in that the ratio R of weft yarn density to warp yarn density is 0.67≦R≦0.97 or 1.03≦R≦1.50.
