Patent ID: 7253559

Claim:
A plasma display panel (PDP), comprising: an upper glass substrate; a sustain electrode formed on a portion of the upper glass substrate; a bus electrode formed on a portion of the sustain electrode; an upper dielectric layer formed conformal to the bus electrode, the sustain electrode, and the upper glass substrate; and a passivation layer formed on the upper dielectric layer, wherein the upper dielectric layer of the PDP is a single layer configured to increase a transmittance of visible light having a blue color wavelength to a higher degree than that of visible light having red and green color wavelengths, and wherein a composition of the upper dielectric layer consists essentially of: a ceramic composition which consists of 55 weight %-72 weight % of PbO, 1 weight %-21 weight % of SiO 2 , 4.2 weight %-20 weight % of B 2 O 3 , 1 weight %-7 weight % of Al 2 O 3 , 0 weight %-0.5 weight % of MgO, 0 weight %-0.5 weight % of CaO, 0 weight %-9 weight % of ZnO; and a coloration additive which consists of 0 weight %-3 weight % of CoO, greater than 0 weight %-3 weight % of Co 3 O 4 , and greater than 0 weight %-23 weight % of Nd 2 O 3 .
