Summary: | A light-emitting device (100) includes a photoluminescent layer (110), a light-transmissive layer (120) located on or near the photoluminescent layer (110), and a submicron structure that is formed on at least one of the photoluminescent layer (110) and the light-transmissive layer (120) and extends in a plane of the photoluminescent layer (110) or the light-transmissive layer (120). The submicron structure has projections or recesses, light emitted from the photoluminescent layer (110) includes first light having a wavelength » a in air, and the distance D int between adjacent projections or recesses and the refractive index n wav-a of the photoluminescent layer (110) for the first light satisfy » a /n wav-a < D int < » a . |
