摘要：
The present invention is intended to provide a light emitting device which can be operated at a low voltage, has excellent luminous efficiency, stability, production cost, and the like. A light emitting device which has at least electrode layers 11, 14, a light emitting layer 13, a structure layer 12 between the electrode layer 11 and light emitting layer 13, wherein structure layer 12 has domains composed of a first material, and domains composed of a second material. It is preferable for the structure layer to have a plurality of columnar domains composed of the first material, and the domains composed of the second material around the domains composed of the first material, and for the domains composed of the first material are arranged regularly. It is preferable that the first material and the second material are composed of different oxides.
