PURPOSE: An organic electroluminescence compound is provided to provide high luminous efficiency, high brightness, high color purity and remarkably improved lifetime. CONSTITUTION: An organic electroluminescence compound comprises a first electrode, a second electrode, and at least one organic layer inserted between the first electrode and the second electrode. The organic layer comprises an organic electroluminescence compound represented by chemical formula F. In chemical formula F, X is O, S, SE or Si, each of R, A1, A2, B1, B2, C1, C2, D1, D2, E1 and E2 is selected from H, D, F, C1-40 alkyl, C5-40 aryl, C5-40 heteroaryl, C5-40 arloxy, C1-40 alkyloxy, C5-40 arylamino, C6-40 arylalkyl, C5-40 ketone, C5-40 arylketone, C3-40 cycloalkyl and C3-40 heterocycloalkyl, or a group forming a fused aliphatic ring, fused aromatic ring, fused heteroaliphatic ring or fused heteroaromatic ring together with a neighboring group. |
