Material for forming barrier ribs, barrier ribs formed using the material and PDP comprising the barrier ribs

A photosensitive barrier rib paste comprising:

• a glass frit composition comprising P2O5 in an amount from about 40 to about 70 parts by weight, SrO in an amount from about 1 to about 20 parts by weight, ZnO in an amount from about 1 to about 30 parts by weight and Al2O3 in an amount from about 1 to about 15 parts by weight,
• a filler, and
• a photosensitive organic material
• wherein the refractive index of the glass frit composition is from about 1.5 to about 1.6
• wherein the reflective index of the photosensitive organic material is from about 1.5 to about 1.6;
• and wherein the glass frit composition comprises an alkali-based metal oxide selected from the group consisting of Li2O, Na2O and K2O, wherein the alkali-based metal oxide is about 3 parts by weight or less.
