Transparent organic electroluminescent element and production method therefor

摘要

A transparent organic EL element comprising: a transparent substrate, a first transparent electrode layer formed on the transparent substrate in stripe form, an insulating partition wall formed in stripe form in a direction orthogonal to the longitudinal direction of the first transparent electrode layer on the transparent substrate with the first transparent electrode layer formed, an organic EL layer including a light emitting layer and formed on the first transparent electrode layer in the light emitting region between the partition walls, a second transparent electrode layer formed on the organic EL layer and divided with the partition wall, and a first auxiliary electrode group formed on the second transparent electrode layer with a plurality of metal fine lines disposed parallel with each other, characterized in that an angle θ1 is 0°<θ1<90°.
