摘要：
The present invention provides a light-emitting device which includes, in the order mentioned, a light-emitting layer containing a light-emitting portion, an intermediate layer, and a fine concavo-convex pattern, wherein the intermediate layer is disposed over a second surface of the light-emitting layer which surface is opposite to a first surface of the light-emitting layer, wherein the fine concavo-convex pattern has a cross-sectional shape which has portions projected and recessed with respect to the light-emitting layer, and reflects light emitted from the light-emitting layer, and wherein at least part of the intermediate layer has a refractive index of 0.9n to 1.1n, where n denotes a refractive index of the light-emitting portion with respect to light which has a main light-emitting wavelength.
