Abstract:
A light-emitting device includes a support substrate which includes a light-emitting layer and a light extraction surface, and a light transmission layer, formed on the light extraction surface of the support substrate, having a periodic refractive index distribution structure in an in-plane direction and a thickness direction, the light transmission layer including a plurality of projections formed of a having a refractive index lower than that of the support substrate.
