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 hole transport region includes a polycyclic compound represented by Formula 5 or Formula 6, thereby showing high emission efficiency.
