Provided are a heterocyclic compound represented by Formula 1 below and an organic electroluminescent device including an organic layer comprising the heterocyclic compound: n n n n n n n n n n n n wherein Ar 1 , Ar 2 , Ar 3 , R 1 , and R 2 are the same as defined in the detailed description. The heterocyclic compound represented by Formula 1 has excellent electrical characteristics and an excellent charge transporting capability, and thus the heterocyclic compound of Formula 1 can be used as a hole injecting material, a hole transporting material, and/or a light emitting material that are suitable for all-color fluorescent and phosphorescent organic light emitting devices such as red, green, blue, and white fluorescent and phosphorescent organic light emitting devices. In addition, the organic electroluminescent device including an organic layer comprising the heterocyclic compound represented by Formula 1 can have a high efficiency, a low driving voltage, and high luminosity. |
