Abstract
A light-emitting device includes: at least one light-emitting element comprising a semiconductor layered portion and configured to emit light that has a predetermined wavelength and includes a first polarization component and a second polarization component; and at least one polarized light control member in contact with the at least one light-emitting element. The at least one polarized light control member includes a first structure and a second structure that are positioned in order from a light-emitting element side. The first structure is configured to receive the light having the predetermined wavelength to generate near-field light. The second structure is configured to receive the near-field light and the light having the predetermined wavelength to emit light in which a proportion of the second polarization component is greater than a proportion of the first polarization component.
