Light-emitting diode and light-emitting device including the same
A light emitting diode includes a first electrode and a second electrode facing the first electrode. The light emitting diode further includes an emitting material layer (EML) disposed between the first electrode and the second electrode, and an electron transport layer (ETL) adjacent the EML. The ETL includes a plurality of first inorganic particles having a first average particle size, and a plurality of second inorganic particles having a second average particle size greater than the first average particle size. The plurality of first inorganic particles may also have a first energy bandgap, and a plurality of second inorganic particles may also have a second energy bandgap smaller than the first energy bandgap.
