ORGANIC EL ELEMENT AND METHOD FOR MANUFACTURING SAME |
摘要 |
In an organic EL element 30, a concave-convex pattern layer 12 having a first concave-convex shape, a first electrode 16, an organic layer 18, and a second electrode layer 20 are stacked on a substrate 10 in this order. Further, an auxiliary layer 14 is provided between the concave-convex pattern layer 12 and the first electrode 16. A surface of the auxiliary layer 14 on the first electrode side has a second concave-convex shape. The change ratio of the standard deviation of depths of the second concave-convex shape with respect to the standard deviation of depths of the first concave-convex shape is 70% or less. The organic EL light-emitting element, which has a high light extraction efficiency while preventing the occurrence of a leak current, can be obtained. |
