El organic encapsulation material and the use of lead-free glass el organic its display

Object of the present invention is to provide an organic EL in terms of a lead-free glass material for encapsulating, a good seal can be obtained by laser sealing quality without adding a metal powder, is excellent in stability at low temperature softening and melting, and thermal expansion also small coefficients, while sufficiently suppressing the adverse effects of heat of the organic EL element, and does not require tight sealing condition of the management and control, which can reach a high yield, high sealing strength and high sealability. Solving means which is represented by mol%, with 30 to 60% comprising V2O5,5 ~ 20% of ZnO, 5 ~ 20% of BaO, 15 ~ 40% of TeO2,0 ~ 7% of Nb2O5,0 ~ 7% Al2O3,0 ~ 5% of SiO2,0 ~ 5% of MgO, 0 ~ 5% of Sb2O3,0 ~ 4% of CuO, 0 ~ 4% of SnO, and Nb2O5 + Al2O3 is 0.5 ~ 10%, SiO2 + MgO + Sb2O3 is 0 ~ 5%, CuO + SnO 0 to 4% of the glass composition of the formed organic EL lead-free glass material for encapsulation.
