GLASS FOR SCATTERING LAYER OF ORGANIC LED ELEMENT, AND ORGANIC LED ELEMENT

摘要

A glass used for a scattering layer of an organic LED element, and an organic LED element using the scattering layer are provided. The present invention relates to an organic LED element including a transparent substrate, a first electrode, an organic layer, and a second electrode in this order, which includes a scattering layer including, in terms of mol% on the basis of oxides thereof: 15 to 30 % of P 2 O 5 ; 5 to 30 % of Bi 2 O 3 ; 5 to 27 % of Nb 2 O 5 ; and 4 to 40 % of ZnO, wherein a total content of alkali metal oxides consisting of Li 2 O, Na 2 O, and K 2 O is 5 mass% or less.
