Patent ID: 6916552

Claim:
An organic electroluminescent device comprising at least a hole transporting layer and a luminescent layer held between an anode and a cathode in a state of lamination in that order from the anode side, wherein: the luminescent layer comprises a spiro compound represented by the following Structural formula (1) and the hole transporting layer consists essentially of triphenylainine tetramer represented by the following Structural formula (2) or the following Structural formula (3): where Ar1 to Ar4 in the Structural formula (1) independently represent a biphenyl group, a substituted biphenyl group, a naphthyl group, a substituted naphthyl group, an anthryl group, or a substituted anthxyl group, and R21 to R26 in the Structural formula (2) and R31 to R36 in the Structural formula (3) independently represent a hydrogen, an alkyl group having the number of carbon atoms of 1 to 12, a cycloalkyl group, an aryl group having the number of carbon atoms of 5 to 28, or a substituted aryl group.
