A carbazole-based compound is provided to show excellent electrical characteristics and charge transport capacity, thereby being useful as a material for forming a charge injection layer, a charge transport layer and/or a luminescent layer. An organic light emitting diode comprising the same carbazole-based compound is provided to exhibit high efficiency, low voltage and high brightness. A carbazole-based compound is represented by a formula(1), wherein each R1, R2, R3, R4, R5, R6, R7, R8, R9, R10, R11, R12, R13 and R14 is independently H, substituted or unsubstituted C1-30 alkyl, substituted or unsubstituted C2-30 alkenyl, substituted or unsubstituted C2-30 alkynyl, substituted or unsubstituted C1-30 alkoxy, substituted or unsubstituted C6-30 aryloxy, substituted or unsubstituted C6-30 aryl, or substituted or unsubstituted C2-30 heteroaryl, optionally the R1, R2, R3, R4, R5, R6, R7, R8, R9, R10, R11, R12, R13 or R14 may form a saturated or unsaturated carbon ring by being coupled to an adjacent group each other. An organic light emitting diode comprises: a first electrode; a second electrode; and an organic film interposed between the first and second electrodes, wherein the organic film includes the carbazole-based compound.
