Light emitting device, projector, and display

A light emitting device comprising:

• a substrate;
• and
• a laminated structure including a plurality of columnar parts, wherein
• the columnar part includes
• a first semiconductor layer of a first conductivity type,
• a second semiconductor layer of a second conductivity type different from the first conductivity type, and
• a light emitting layer disposed between the first semiconductor layer and the second semiconductor layer,
• the first semiconductor layer is disposed between the substrate and the light emitting layer,
• the light emitting layer has a c-plane and a facet plane,
• the second semiconductor layer is disposed on the c-plane and the facet plane,
• the first semiconductor layer has a first portion and a second portion smaller in diametrical size than the first portion,
• the second portion is disposed between the substrate and the first portion, and
• the c-plane and the second portion overlap each other, and the c-plane is smaller in diametrical size than the second portion in a plan view from a stacking direction of the first semiconductor layer and the light emitting layer.
