US 7,442,803 B2 · Aromatic amine compound, and light emitting element, light emitting device, and electronic device using aromatic amine compound

Abstract

An object is to provide an aromatic amine compound with excellent heat resistance. Another object is to provide a light emitting element, a light emitting device, and an electronic device with excellent heat resistance. An aromatic amine compound represented by General Formula (1) is provided. The aromatic amine compound represented by General Formula (1) has a high glass transition point and excellent heat resistance. By using the aromatic amine compound represented by General Formula (1) for a light emitting element, a light emitting device, and an electronic device, a light emitting element, a light emitting device, and an electronic device with excellent heat resistance can be obtained.
