An organic electroluminescence device includes a first electrode, a hole transport region on the first electrode, an emission layer on the hole transport region, the emission layer including a condensed polycyclic compound of three or more six-membered rings, at least two six-membered rings among the six-membered rings including an electron donor moiety and an electron acceptor moiety at facing positions, respectively, the at least two six-membered rings not being immediately adjacent to each other, an electron transport region on the emission layer, and a second electrode on the electron transport region.
