Provided are a compound represented by Formula 1 or 2 below and an organic light emitting device including an organic layer having the compound: Formula 1 Formula 2 where Ar1, Ar2, Ar3, R1, R2 and R3 are as described in the detailed description. Since the compound represented by Formula 1 or 2 has excellent electrical properties and excellent charge transport capabilities, the compound can be efficiently used as a hole injecting material, a hole transporting material, and/or an emitting material which is suitable for a fluorescent or phosphorescent organic light emitting device which can realize all colors such as red, green, blue, and white. Thus, an OLED including the compound can have high efficiency, high current density, low driving voltage, excellent brightness, and long lifetime. |
