Abstract:
By using a polycyclic aromatic compound as a material for a light-emitting layer, formed by connecting a plurality of aromatic rings with a boron atom and an oxygen, sulfur, or selenium atom, which have been substituted by a specific aryl such as anthracene, an organic EL element having at least one of excellent quantum efficiency and element life can be provided.
