Micro light emission element and image display device

A micro light emission element comprising:

• a compound semiconductor in which a first conductive layer, a light emission layer, and a second conductive layer having a conductivity type opposite to a conductivity type of the first conductive layer are sequentially laminated from a side of a light emitting surface, wherein
• a first electrode coupled to the first conductive layer and a second electrode coupled to the second conductive layer are disposed on another surface opposite to the light emitting surface,
• the second electrode is disposed on the light emission layer,
• the first electrode is disposed in an isolation region which is a boundary region of the micro light emission element and isolates the light emission layer from a light emission layer of another micro light emission element,
• a surface of the first electrode on a side of the other surface and a surface of the second electrode on the side of the other surface are flush with each other and are made of an identical material,
• in the first electrode, a first metal material is disposed on the side of the light emitting surface, and a second metal material is disposed on the side of the other surface, and
• the first metal material has a higher reflectance as compared to the second metal material.
