1. A plasma display filter comprising:

  • a substrate; and

    a sequence of layers on said substrate, said sequence including at least six dielectric layers and at least five metallic layers, said dielectric and metallic layers being disposed in an alternating pattern in which one of said dielectric layers is the layer of said alternating pattern closest to said substrate;

    wherein a combined thickness of said metallic layers in said alternating pattern is greater than 50 nm and wherein individual thicknesses of said metallic layers and said dielectric layers define filter properties that include;

    (a) a reflected color Ra* of less than 20 throughout a range of 0 degrees to 60 degrees angle of incidence; and

    (b) a sheet resistance in a range of 0.5 ohms/square and 1.5 ohms/square.
