The present invention relates to an organic electroluminescent device comprising at least one light-emitting layer between an anode and a cathode, wherein the light-emitting layer comprises a host and a dopant; the host consists of multi-component host compounds; at least a first host compound of the multi-component host compounds is a specific bicarbazole derivative containing an aryl group, and a second host compound is a specific carbazole derivative including a nitrogen-containing heteroaryl group. According to the present invention, an organic electroluminescent device using the multi-component host compounds has a high efficiency and long lifespan compared to the conventional organic electroluminescent device using one component of a host.
