Patent ID: 7224123

Claim:
A method for fabricating an upper substrate for a plasma display panel comprising the steps of: depositing indium tin oxide (ITO) on an upper glass substrate, and patterning the same to form a sustain electrode; forming a bus electrode on some upper part of the sustain electrode; forming an upper substrate dielectric layer including colorant which reinforces color properties of red, blue, and green colors on a lower entire surface of the sustain electrode, the bus electrode, and the upper glass substrate; and forming a protection layer on a lower part of the dielectric layer; wherein the upper dielectric layer is formed by mixing 45˜70% of PbO, 1˜10% of SiO 2 , 5˜30% of B 2 O 3 , 0.1˜5% of Al 2 O 3 , and 0.1˜25% of colorant.
