Light-emitting element

摘要

A light-emitting element (10) includes a light-emitting layer (2) including a base layer (3) made of a first nitride semiconductor and plural island-shaped crystal portions (4) made of a second nitride semiconductor, and an irradiation source (5) of electron beam which is disposed so as to be opposite to the light-emitting layer (2). Then, electron-electron hole pairs in the light-emitting layer (2) are excited through the irradiation of electron beam from the irradiation source (5), to generate and emit a light.
