PURPOSE: A novel carbazole derivative is provided to apply to an organic light emitting device, to lower driving voltage, and improve light efficiency. CONSTITUTION: A novel carbazole derivative is denoted by chemical formula 1. An organic light emitting device comprising a substrate(1), anode(2), light emitting layer(3), and cathode(4) has laminated form of a first electrode, organic layer, and second electrode. The organic layer contains the carbazole derivative compound or a compound having a functional group of thermosetting or photocurable property.
