Abstract
A light-emitting device includes: a light-emitting element including a transparent electrode, a reflecting electrode, and an organic layer that includes a light-emitting layer; a transparent multilayer body including a low-refractive-index layer and a high-refractive-index layer, the high-refractive-index layer being provided in contact with the transparent electrode; a first uneven structure at an interface between the low-refractive-index layer and the high-refractive-index layer, the first uneven structure including depressions and projections, a height of each of the projections relative to the depressions being 400 nm or more; and a second uneven structure at an interface between the reflecting electrode and the organic layer, the second uneven structure including depressions and projections, a height of each of the projections relative to the depressions in the second uneven structure being 20 nm or more and 100 nm or less.
