Abstract
An electroluminescent device including a first electrode, a hole transport layer disposed on the first electrode, a first emission layer disposed on the hole transport layer, the first emission layer including a first light emitting particle on which a first ligand having a hole transporting property is attached, a second emission layer disposed on the first emission layer, the second emission layer including a second light emitting particle on which a second ligand having an electron transporting property is attached, an electron transport layer disposed on the second emission layer, and a second electrode disposed on the electron transport layer, wherein a solubility of the first ligand in a solvent is different than a solubility of the second ligand in the solvent and a display device including the same.
