Patent ID: 6926574

Claim:
A method of forming a plurality of stripe-shaped first electrodes of a plasma display panel comprising a front substrate comprising a transparent first insulating substrate made of float glass and the plurality of stripe-shaped first electrodes extending parallel to each other, and a rear substrate comprising a second insulating substrate, a plurality of second electrodes extending parallel to each other and being formed on the second insulating substrate, and a plurality of ribs formed on the second insulating substrate separating adjacent second electrodes of the plurality of second electrodes and forming a plurality of discharge spaces therebetween, wherein the front substrate and the rear substrate are formed upon each other and the plurality of stripe-shaped first electrodes extend generally perpendicular to the plurality of second electrodes, said method of forming the plurality of stripe-shaped first electrodes comprising: forming a plurality of stripe-shaped transparent electrodes on the transparent first insulating substrate; applying a first conductive paste layer containing ruthenium oxide or a compound made of ruthenium on the plurality of stripe-shaped transparent electrodes; firing the first conductive paste layer thereby forming a black-colored first conductive layer; applying a second conductive paste layer containing silver on the black-colored first conductive layer so that the second conductive paste layer has a width smaller than that of the black-colored first conductive layer; and firing the second conductive paste layer thereby forming a second conductive layer having a lower resistivity than the black-colored first conductive layer and also having a width smaller than that of the black-colored first conductive layer.
