Abstract:
A novel dibenzocarbazole compound with which a light-emitting element having low power consumption, high reliability, and high color purity can be fabricated is provided. In the dibenzocarbazole compound, an aryl group which has 14 to 30 carbon atoms and at least an anthracene skeleton is bonded to nitrogen of a dibenzo[a,g]carbazole skeleton or a dibenzo[a,i]carbazole skeleton. Furthermore, a light-emitting element including the dibenzocarbazole compound is provided.
