Lead-free acid-resistant glass composition and glass paste comprised of the same

A plasma display panel comprising a first substrate and a second substrate opposed to each other, an address electrode disposed on the first substrate, a white dielectric layer covering the address electrode, a discharge retaining electrode disposed on the second substrate, a dielectric layer covering the discharge retaining electrode, a protection layer disposed on the dielectric layer, a partition wall disposed between the first and second substrates so as to divide a space between the first and second substrates into a plurality of discharge cells, fluorescent layers formed in the discharge cells for respectively emitting red, green and blue lights;

• the white dielectric layer being made of lead-free acid-resistant glass composition including 5-25% of SiO2, 4-30% of B2O3, 7-30% of ZnO, 15-70% of Bi2O3, 0-15% of Al2O3, 5-20% of BaO in weight percentage, and being substantially lead-free.
