A Pb-free glass composition for plasma display panel(PDP) is provided, which has low sintering temperature, high water resistance and effective linear expansion coefficient by using P2O5, ZnO and SnO as main materials. The Pb-free glass composition comprises 30-50mol% of P2O5, 20-50mol% of ZnO for stabilization of glass and 15-45mol% of SnO for decrease of glass transition temperature and increase of linear expansion coefficient, wherein 5-10mol% of SiO2 and 5-10mol% of B2O3 as glass forming materials are optionally added to the composition. The resultant glass composition is used as transparent dielectric glass composition, sealing glass composition, barrier rib or white dielectric glass composition.
