Abstract
An organic electroluminescence device includes a first electrode, a hole transport region disposed on the first electrode, an emission layer disposed on the hole transport region, an electron transport region disposed on the emission layer, and a second electrode disposed on the electron transport region, wherein the emission layer includes a polycyclic compound containing two electron donors and one electron acceptor, and the electron acceptor includes a benzonitrile part and a pyridine part, thereby showing high emission efficiency.
