1. A plasma display device comprising:

  • a plasma display panel (PDP); and

    an electromagnetic interference (EMI) filter provided at a front portion of the plasma display panel, the EMI filter including an EMI coating supported by a glass substrate, the EMI coating including layers moving away from the glass substrate including;

    a first high index layer having a refractive index (n) of at least about 2.2;

    a first silicon-inclusive layer;

    a first layer comprising zinc oxide;

    a first EMI shielding layer comprising silver contacting the first layer comprising zinc oxide;

    a first layer comprising an oxide of Ni and/or Cr contacting the first EMI shielding layer comprising silver;

    a first metal oxide layer;

    a second silicon-inclusive layer;

    a second layer comprising zinc oxide;

    a second EMI shielding layer comprising silver contacting the second layer comprising zinc oxide;

    a second layer comprising an oxide of Ni and/or Cr contacting the second EMI shielding layer comprising silver;

    a second metal oxide layer;

    a third silicon-inclusive layer;

    a third layer comprising zinc oxide;

    a third EMI shielding layer comprising silver contacting the third layer comprising zinc oxide;

    a third layer comprising an oxide of Ni and/or Cr contacting the third EMI shielding layer comprising silver; and

    a third metal oxide layer;

    a fourth silicon-inclusive layer;

    a fourth layer comprising zinc oxide;

    a fourth EMI shielding layer comprising silver contacting the third layer comprising zinc oxide;

    a fourth layer comprising an oxide of Ni and/or Cr contacting the third EMI shielding layer comprising silver,wherein the EMI filter has a sheet resistance of greater than about 1.2 ohms/square, andwherein thicknesses of both the first and fourth EMI shielding layers are less than thicknesses of the second and third EMI shielding layers.
