Provided are an organometallic compound, an organic light-emitting device including the organometallic compound, and an organic light-emitting apparatus including the organic light-emitting device. Organic light-emitting devices including the organometallic compound may have a low driving voltage, high efficiency, and high luminance, thereby implementing high-quality organic light-emitting devices and organic light-emitting apparatuses.
A novel organic compound is provided. That is, a novel organic compound that is effective in improving reliability of a light-emitting element is provided. The organic compound includes a condensed ring including a pyrimidine ring and is represented by General Formula (G1). In General Formula (G1), A represents a group having 6 to 100 carbon atoms and includes at least one of an aromatic ring and a heteroaromatic ring. The aromatic ring and the heteroaromatic ring may each include a substituent. Furthermore, Q represents oxygen or sulfur. A ring X represents a substituted or unsubstituted naphthalene ring or a substituted or unsubstituted phenanthrene ring.
An organic light-emitting device includes: a first electrode; a second electrode facing the first electrode; and an organic layer between the first electrode and the second electrode and including an emission layer. The emission layer includes at least one doping layer and at least one non-doping layer. The doping layer comprises a first host, a second host, and a dopant.
