Abstract: The present invention provides a transparent EMI shielding film that includes a first transparent polymeric substrate layer. A first conductive mesh layer having a first pattern is printed on the first layer, the conductive mesh having a line width from approximately 5 μm to approximately 500 μm and having a space between two adjacent conductive lines of 100 μm to 1000 μm. The conductive mesh blocks electromagnetic signals. A second transparent polymeric layer is positioned over the first transparent polymeric substrate layer having the first conductive mesh layer printed thereon. A second conductive mesh layer having a second pattern is printed on the second transparent polymeric layer, the second pattern being substantially identical to the first pattern, and being substantially identically positioned above the first pattern in order to maximize transparent spaces between adjacent conductive lines. The transparency is approximately 80% or greater in a visible light spectral region.
