A light-emitting device includes: a light-transmitting substrate (10) having a light extraction surface and a concavoconvex surface formed on the side opposite the light extraction surface; reflective films (20) covering portions of the concavoconvex surface; a high refractive index layer (30) provided on the light-transmitting substrate (10) with the concavoconvex surface and the reflective film (20) surfaces as the interface therebetween, and having a higher refractive index than that of the light-transmitting substrate (10); an organic functional layer (50) containing a light-emitting layer and provided on the high refractive index layer (30); and a reflective electrode (60) provided on the organic functional layer (50). Each reflective film (20) forms a light-reflecting surface angled in relation to the light extraction surface and positioned along the interface between the light-transmitting substrate (10) and the high refractive index layer (30). A light-transmitting surface angled in relation to the plane in which the light-emitting layer extends is formed along the interface between the light-transmitting substrate (10) and the high refractive index layer (30). |
