GLASS FOR SCATTERING LAYER OF ORGANIC LED DEVICE AND ORGANIC LED DEVICE

摘要

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 P 2 O 5 , 5 to 25% of Bi 2 O 3 , 5 to 27% of Nb 2 O 5 , and 4 to 35% of ZnO and having a total content of alkali metal oxides including Li 2 O, Na 2 O and K 2 O of 5% by mass or less.
