1. An organic electroluminescence device comprising:
a first electrode;
a second electrode facing the first electrode; and
a plurality of organic layers between the first electrode and the second electrode,
wherein the first electrode and the second electrode each independently comprise at least one selected from Ag, Mg, Cu, Al, Pt, Pd, Au, Ni, Nd, Ir, Cr, Li, Ca, LiF/Ca, LiF/Al, Mo, Ti, In, Sn, Zn, a compound of two or more thereof, a mixture of two or more thereof, and oxides of one or more thereof,
wherein at least one of the organic layers comprises a fused polycyclic compound represented by Formula 1 below:

OG Complex Work Unit Chemistry
wherein in Formula 1 above,
Cy1 to Cy7 are each independently a substituted or unsubstituted aromatic hydrocarbon ring, or a substituted or unsubstituted aromatic heterocycle,
X1 to X4 are each independently NRa, O, or S, and
Ra is a substituted or unsubstituted alkyl group having 1 to 20 carbon atoms, a substituted or unsubstituted aryl group having 6 to 60 ring-forming carbon atoms, or a substituted or unsubstituted heteroaryl group having 1 to 60 ring-forming carbon atoms.
