PURPOSE: Provided is an organic electroluminescent device excellent in element stability and luminous efficiency by synthesizing a new blue luminescent material as a material for hole transportation and hole injection. CONSTITUTION: The organic electroluminescence device comprises a first electrode, an organic luminescent layer and a second electrode. In the device, the compound represented by formula 1 is used as blue luminescent material of organic luminescent layer. In the formula 1, R1 is hydrogen or the following formula, and each of Ar1 and Ar2 is selected from the group consisting of aliphatic substituents, aromatic substituents, and hydrogen. The each of Ar1 and Ar2 is selected from the group consisting of a phenyl group, a naphthyl group, and a phenanthryl group.
