PURPOSE: Glass frit, a glass frit paste composition for sealing an electric device, and a sealing method of the electric device using the glass frit paste composition are provided to secure the excellent sealing effect of the glass frit for the moisture and gas. CONSTITUTION: Glass frit contains 15~35mol% of ZnO, 0.01~5mol% of BaO, 0.01~5mol% of CaO, 0.1~5mol of NiO, 0.01~5mol% of SrO, 0.1~5mol% of Al2O3, 0.1~5mol% of B2O3, 50~70mol% of V2O5, 0.1~10mol% of K2O, 0.1~10mol% of Li2O, and 1~15mol% of Na2O. A glass frit paste composition contains 40~90wt% of glass frit, 0.1~5wt% of organic binder, and 5~55wt% of organic solvent. A sealing method of an electric device comprises a step of printing the glass frit paste composition on a sealing position, and a step of fusing the glass frit paste composition with a laser.
