A composition of paste and a green sheet for forming double-layered barrier ribs for use in PDPs, and the PDPs using the same is provided. A composition of paste for use in barrier ribs in PDPs comprises about 30 wt % to 60 wt % of a Pb-free glass powder, about 1 wt % to 10 wt % of a filler, about 10 wt % to 30 wt % of a binder, about 1 wt % to 8 wt %/o of a plasticizer, about 0.1 wt % to 3 wt % of a dispersing agent, and about 15 wt % to 35 wt % of a solvent. The PDPs comprises a lower substrate and a upper substrate oppositely disposed each other, address electrodes formed on the lower substrate, and discharge electrodes formed on the upper substrate, barrier ribs disposed in the area between the lower substrate and the upper substrate to divide a plurality of discharge cells, and a red, green and blue fluorescent substance layer formed in the discharge cell divided by the barrier ribs. The barrier ribs are formed by a paste composition comprising about 30 wt % to 60 wt % of a Pb-free glass powder, about 1 wt % to 10 wt % of a filler, about 10 wt % to 30 wt % of a binder, about 1 wt % to 8 wt % of a plasticizer, about 0.1 wt % to 3 wt % of a dispersing agent and about 15 wt % to 35 wt % of a solvent.
