Light emitting device and manufacturing apparatus of light emitting device

In order to provide a light-emitting device which easily brings about energy transition and improves light emission efficiency in a fluorescent material having a light emission spectrum peak in the deep blue region, this light-emitting device (2) comprises a light-emitting layer (10) in which quantum dots (22) and fluorescent or phosphorescent luminous bodies (22) are dispersed, a first electrode (4) in a layer below the light emitting layer (10), and a second electrode (16) in a layer above the light-emitting layer (10), wherein there is at least partial overlap between the light emission spectrum of the quantum dots (20) and the absorption spectrum of the luminous bodies (22).
