  • Patent number: 10777774
    Abstract: A light emitting element and corresponding display device with improved light extracting efficiency are disclosed. In one example, a light emitting element includes a first electrode with a first member disposed on both sides to form a recess structure with the first electrode as a bottom. An organic light emitting layer is disposed along the recess structure on the first electrode and the first member, and a second electrode is disposed on the organic light emitting layer. A second member having a higher refractive index than the first member is disposed on the second electrode so as to embed the recess structure. Between the second electrode and the second member, a laminate barrier layer is formed of layers having different refractive indices and having, as the entire laminate, a refractive index between the refractive index of the second electrode and the refractive index of the second member.
