1. An organic electroluminescence device, comprising:
a first electrode;
a second electrode disposed on the first electrode; and
at least one organic layer disposed between the first electrode and the second electrode;
wherein
the at least one organic layer comprises a polycyclic compound having a core structure including a n,n′-bicarbazole moiety and at least one substituted or unsubstituted carbazole group, and
the substituted or unsubstituted carbazole groups are substituted at any one among carbon atoms at position n±1 of the n,n′-bicarbazole moiety, and any one among carbon atoms at position n′±1 of the n,n′-bicarbazole moiety, respectively; and
n and n′ are, independently from one another, integers of 1, 2, or 4, wherein n+1 and n′+1 are not 0.
