Abstract
Provided is a light-emitting device having a structure in which a high refractive index component is provided between a solid light-emitting element and air, has an uneven structure on a surface in contact with air, and can be reused. The light-emitting device includes a substrate having a refractive index of 1.6 or higher and a light-transmitting property, a solid light-emitting element including a light-emitting region having a refractive index of 1.6 or higher on one surface of the substrate, and a component having a refractive index of 1.6 or higher and a light-transmitting property on the other surface of the substrate, wherein the component includes an uneven structure on a surface in contact with air and is connected to the substrate via a liquid having a refractive index of 1.6 or higher and a light-transmitting property.
