Abstract
The present disclosure relates to a coating-type organic electroluminescent device and a display device and a lighting device including the same. The present disclosure relates to an organic electroluminescent device in which an inter-electrode layer and at least one layer of a first electrode and a second electrode can be consistently manufactured at atmospheric pressure. The organic electroluminescent device includes a first electrode, an electron injection layer facing the first electrode, and an emitting material layer located between the first electrode and the electron injection layer, wherein the emitting material layer and the electron injection layer are formable by coating.
