Abstract:
A glass to be used in a scattering layer of an organic LED element, and an organic LED element using the scattering layer are provided. The organic LED element of the present invention includes, a transparent substrate, a first electrode provided on the transparent electrode, an organic layer provided on the first electrode, and a second electrode provided on the organic layer, and further includes a scattering layer including, in terms of mol % on the basis of oxides, 15 to 30% of P2O5, 5 to 25% of Bi2O3, 5 to 27% of Nb2O5, and 10 to 35% of ZnO and having a total content of alkali metal oxides including Li2O, Na2O and K2O of 5% by mass or less.
