A dielectric composition for a dielectric layer in a plasma display panel comprising glass powder including Nd2O3.
A dielectric composition for a dielectric layer in a plasma display panel, wherein the plasma display panel comprises an upper glass substrate, a sustain electrode on the upper glass substrate, a bus electrode on the sustain electrode, a lower glass substrate, a lower dielectric layer and an address electrode on the lower glass substrate, a fluorescent layer on the lower dielectric layer and on the address electrode, and a barrier rib on the lower dielectric layer, comprising:
- a glass of P2O5—B2O3—ZnO group;
- and
- a filler consisting of Nd2O3.
A method for fabricating a dielectric layer in a plasma display panel comprising the steps of:
- fabricating a glass by mixing Nd2O3 with a glass of P2O5—B2O3—ZnO group as a predetermined weight %;
- making the fabricated glass into powder by grinding, and forming a dielectric paste by mixing the powder with a binder, and with a solvent;
- applying the paste on a glass substrate;
- and
- baking the applied dielectric paste to form the dielectric layer.
