The present invention provides a flexible light-emitting device which is a flexible device with which the light leakage is less liable to occur even if it is deformed. In order to achieve the above object, the flexible light-emitting device of the present invention includes a light-emitting layer, a low refractive index layer, and a high refractive index layer, wherein the light-emitting layer, the low refractive index layer, and the high refractive index layer are stacked in this order, the low refractive index layer has a refractive index lower than that of the light-emitting layer and has a haze of less than 5%, and the high refractive index layer has a refractive index higher than that of the low refractive index layer.
