Abstract: A light emitting element including a first electrode, a second electrode on the first electrode, and at least one functional layer between the first electrode and the second electrode is provided. The at least one functional layer may include an amine compound represented by Formula 1. Accordingly, the light emitting element may exhibit a long service life characteristic. In addition, the light emitting element may exhibit characteristics in which the driving voltage is reduced, and the brightness and efficiency are improved.
