Paragraph 0573-0579, (2020/11/28)
PURPOSE: A carbazole derivative is provided to drive an organic electroluminescent device at low voltage and to improve brightness when the derivative is used in an organic layer of the organic electroluminescent device, thereby improving economic efficiency. CONSTITUTION: A carbazole derivative is denoted by chemical formula 1. An organic electroluminescent device comprises a first electrode, a second electrode, and one or more organic layers between the first and second electrodes. The organic layers contain the carbazole derivative of chemical formula 1. The organic layers are selected among a hole injection layer, a hole transport layer, a functional layer with hole injecting and transporting functions, a light emitting layer, an electrode transport layer, and an electron injection layer. The light emitting layer contains one or more host compounds and one or more dopant compounds. The host compound is a carbazole derivative of chemical formula 1.
