A glass composition for vacuum exhaust/sealing of plasma display panel is provided to have excellent adhesive force and to be environment-friendly because Pb is not included. A glass composition for vacuum exhaust/sealing of plasma display panel comprises: (a) ZnO; (b) a compound selected from a group consisting of SnO, SnO2 and (c) a mixture thereof; and ammonium salt. A weight ratio of (a), (b) and (c) is 1 to 10 : 20 to 80 : 5 to 60. The ammonium salt is a compound selected from a group consisting of NH4H2PO4, (NH4)2HPO4 and a mixture thereof. The glass composition for vacuum exhaust/sealing of plasma display panel additionally includes component selected from a group consisting of MgO, CaO, SrO, Al2O3, CeO2, La2O3, TiO2, SiO2, B2O3, Li2O, Na2O and a mixture thereof. |
