Abstract:

A plasma display filter includes five metallic layers, such as silver alloy layers, having a combined thickness that exceeds 50 nm. The metallic layers form an alternating pattern with dielectric layers, where the layer in the pattern closest to a supporting substrate is the first of the dielectric layers. Layer thicknesses are selected to achieve a low reflected color shift with changes in the viewing angle, relatively neutral transmitted color properties, and desirable shielding characteristics with respect to infrared and electromagnetic radiation.
