Abstract:
[Object] To provide a light emitting element that enables efficient light extraction and offers low power consumption.[Solution] A light emitting element including: a lower electrode disposed on a support layer; first members disposed on the support layer so as to surround the lower electrode to form a recess structure, the first members each having a void inside; an organic layer disposed on the lower electrode and the first members and along the recess structure, the organic layer containing an organic luminescent material; an upper electrode disposed on the organic layer and along the recess structure; and a second member disposed above the upper electrode such that the recess structure is embedded in the second member, the second member having a higher refractive index than the first members.
