Paragraph 0184; 0185; 0186, (2013/03/26)
A carbazole-based compound of Formula 1 and an organic light-emitting diode including the same. The carbazole-based compound represented by Formula 1 has a triarylamine structure, wherein at least one of R1 to R5 is essentially a nitrogen-containing group. Thus, the carbazole-based compound has high glass transition temperature and/or high melting point, and is stable during electron injection, and when interposed between a pair of electrodes (anode and cathode) of an organic light-emitting diode, the carbazole-based compound may have excellent thermal resistance against Joule's heat generated in organic layers between the pair of electrodes, between the organic layers, or between the organic layer and the electrode during an operation of the organic light-emitting diode.
