<p>PURPOSE: A condensed cyclic compound is provided to provide an organic light-emitting diode with excellent performance of high luminous efficiency and life time. CONSTITUTION: A condensed cyclic compound is represented by chemical formula 1. In chemical formula 1, X is N or S, Y is N, B and P, A1 and A2 is a bicyclic or aromatic ring, L1, L2 and L3 is independently one of a substituted or unsubstituted C1-30 alkylene group, a substituted or unsubstituted C5-30 arylene group and a substituted or unsubstituted divalent C2-30 heterocyclic group. An organic light-emitting diode comprises a first electrode, a second electrode facing with the first electrode, and at least one or more organic layer inserted between the first electrode and the second electrode. The organic layer comprises the condensed compound.</p> |
