ABSTRACT:
Provided are a carbazole-based compound represented by Formula 1 below and an organic light-emitting device including an organic layer including the carbazole-based compound:wherein R1, R2, R3, R4, R5, R6, R7, R8, R9, R10, R11, R12, R13, and R14are as defined in the specification. The carbazole-based compound has good electrical characteristics and charge transport capability, and thus, is useful as a hole injection material, a hole transport material, and/or an emitting material for fluorescent or phosphorescent devices capable of producing light of a full spectrum of colors, including red, green, blue, and white, thereby making it possible to produce an organic light-emitting device with high efficiency, a low driving voltage, and high brightness.
