Abstract
The present disclosure relates to a light emitting diode in which a charge transfer layer, which disposed between two electrodes, including an inorganic material in which an amphiphilic ligand is connected to a surface of an inorganic nano particle and to a light emitting device having the diode. The amphiphilic ligand minimizes defects on the surface of the inorganic nano particle, thus charge transfer materials can be stably. Since charge transfer layers and an emitting material layer can be prepared by using an orthogonal solvent, interface morphology between the emissive layers can be improved.
