16 Claims

1. An organic electroluminescence device comprising:

a first electrode;

a second electrode on 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/AI, Mo, Ti, In, Sn, and Zn, a compound of two or more selected from them, a mixture of two or more selected from them, and an oxide thereof, and

wherein at least one organic layer among the plurality of organic layers comprises a fused polycyclic compound in which,

a dibenzoheterocyclic derivative and

a monoheterocyclic derivative comprising at least one nitrogen atom as a ring-forming atom

are connected via a linking group, wherein the dibenzoheterocyclic derivative, the monoheterocyclic derivative, and the linking group together form a ring.
