Abstract:
1. A light-emitting element comprising: a member comprising a hemispherical structure on a first surface and an uneven structure on a second surface; a bonding layer planarizing the uneven structure; and a light-emitting body having a light-emitting surface in contact with a flat surface of the bonding layer, wherein the bonding layer has a higher refractive index than the member, wherein the uneven structure of the member is provided at least in a region overlapping with the hemispherical structure, wherein the light-emitting body is provided such that an outside shape of a light-emitting region of the light-emitting body projected on a surface including the light-emitting surface is smaller than an outside shape of the hemispherical structure projected on the surface including the light-emitting surface and overlaps with the hemispherical structure, wherein the outside shape of the light-emitting region of the light-emitting body is concentric with the outside shape of the hemispherical structure, and wherein the outside shape of the light-emitting region of the light-emitting body and the outside shape of the hemispherical structure are similar in shape.
