Abstract: An organic electroluminescent device is provided to exhibit a very good drive life due to excellent luminous efficiency and life characteristic of an organic electroluminescent compound. An organic electroluminescent device has an organic material layer interposed between a positive electrode and a negative electrode on a substrate. The organic material layer comprises at least one organic electroluminescent compound represented by the following formula 1 as a host. In the formula, A and B are, independently of each other, a chemical bond or C6-30 arylene, Ar1 and Ar2 are, independently of each other, phenyl, naphthyl, anthryl, or fluorenyl with or without at least one substituent selected from hydrogen, C1-20 linear or branched alkyl groups or alkoxy groups, C6-30 aryl or heteroaryl groups, and halogen groups, except that both of Ar1 and Ar2 are hydrogen.
