Patent ID: 7906908

Claim:
A Plasma Display Panel (PDP) comprising: a first substrate and a second substrate that are arranged in parallel with each other with a predetermined distance therebetween; a plurality of address electrodes arranged on the first substrate; a first dielectric layer arranged to cover the address electrodes; a plurality of barrier ribs having a predetermined height from the first dielectric layer to define discharge cells; red, blue, and green phosphor layers respectively arranged in the discharge cells; a plurality of display electrodes arranged on one side of the second substrate facing the first substrate in a direction crossing the address electrodes; a second dielectric layer arranged to cover the display electrodes; and a protective layer arranged to cover the second dielectric layer; wherein the second dielectric layer satisfies values of CIE L*a*b* where 70.0<L*<74.5, 0.0<a*<1.0, and −5.0<b*<−8.0, and wherein the second dielectric layer comprises a glass powder composition to form the dielectric layer and a coloring pigment, the coloring pigment comprising 0.27 to 0.35 wt % of Mn 2 O 3 , 0.07 to 0.15 wt % of NiO, and 0.45 to 0.65 wt % of CoO.
