The present invention provides a light emitting device including an organic compound capable of emitting phosphorescence in a light emitting layer. In addition, a light emitting device capable of realizing a low driving voltage, a high current efficiency, or a long life is provided. In the light-emitting element including a light-emitting layer sandwiched between a pair of electrodes, the light-emitting layer contains an organic compound and the organic compound is a 1,2,4-triazole skeleton, a phenyl skeleton, an arylene skeleton, Triazine structure, the nitrogen at the 4-position of the 1,2,4-triazol skeleton is coordinated to the metal of the ninth or tenth group, and the nitrogen at the 1-position of the 1,2,4- Phenyl skeleton, the arylene skeleton binds to the 3-position of the 1,2,4-triazol skeleton, and binds to the ninth or tenth group metal. |
