Light-emitting device, display device, and electronic apparatus

A light-emitting device comprising:

• a first electrode;
• a second electrode that is disposed to face the first electrode and has a light-transmitting property;
• a stacked body that is provided between the first electrode and the second electrode and includes a tapered portion having a tapered shape having a width increasing from a side of the first electrode toward a side of the second electrode;
• a first low refractive index portion that is provided on a side surface of the tapered portion and has a lower refractive index than the stacked body;
• a second low refractive index portion that is provided on a side of the second electrode opposite to the stacked body and has a lower refractive index than the stacked body;
• and
• a metal portion provided on a side surface of the second low refractive index portion, wherein
• the stacked body 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 that is provided between the first semiconductor layer and the second electrode, and
• a light-emitting layer that is provided between the first semiconductor layer and the second semiconductor layer,
• light generated in the light-emitting layer is emitted from the side of the second electrode, and
• a surface of the second low refractive index portion on a side opposite to the second electrode is a lens surface.
