Abstract
Provided are multi-component films useful as optical display filters. The films include a transparent substrate, a nucleation layer, an electrically-conductive layer, a barrier layer, and a dielectric layer. The films can provide high visible transmission, are corrosion-resistant, and can provide shielding from electromagnetic interference (EMI shielding). The optical display filters are useful as components of active optical devices such as display panels including liquid crystal display panels such as those used on mobile hand-held phones.
