    Abstract: A light-emitting device includes a first electrode, an emission layer, an electron transport layer, a metal-nucleation inducing layer, and a second electrode. The metal-nucleation inducing layer is in direct contact with the second electrode, and includes a metal-nucleation inducing material having at least one metal-nucleation inducing group. The second electrode includes a metal-containing film that is hybridized with the metal-nucleation inducing material. The metal-nucleation inducing group is a π electron-deficient nitrogen-containing C1-C60 cyclic group that is unsubstituted or substituted with at least one R1 or a group represented by one of Formulae 1A to 1E, and does not comprise a group represented by *—C(═O)(OH) and a cyano group. The emission efficiency and/or lifespan of the light-emitting device may be improved because of the metal-nucleation inducing layer.

    Abstract: A method of manufacturing an organic light-emitting device by using a solution process is provided. The method entails forming a first organic layer between a first electrode and a second electrode, and forming a second organic layer between the first organic layer and the second electrode. The forming of the first organic layer comprises performing a solution process using a composition comprising a first compound, a second compound, and a solvent. The forming of the second organic layer comprises depositing a third compound on the first organic layer. An absolute value of a difference between a relative polarity of the first compound and a relative polarity of the solvent is about 0.03 or less.
