Title
(EN) Layered, light-emitting element
Abstract
(EN)

A light-emitting element is provided having a layered structure composed of at least a light-emitting layer having a light-emitting region and a reflective layer for reflecting light emitted from the light-emitting region. Light emitted from the light-emitting region is extracted from a light-extracting surface distanced from the light-emitting region. A light-scattering portion is present in a part of the reflective layer.
