Abstract
An organic electroluminescence device of an embodiment includes a first electrode and a second electrode which face each other, and a plurality of organic layers disposed between the first electrode and the second electrode. At least one organic layer selected from the plurality of organic layers includes a fused polycyclic compound represented by Formula 1, and thus the organic electroluminescence device can exhibit improved luminous efficiency.
