Page/Page column 32, (2010/11/24)
An aromatic amine compound having a specific structure represented by the following formula (I); and an organic electroluminescent element comprising a cathode, an anode, and one or more organic thin film layers sandwiched between the electrodes and comprising at least a luminescent layer, wherein at least one of the organic thin film layers consists of the aromatic amine compound alone or contains the compound as a component of a mixture. Due to this constitution, the organic electroluminescent element emits light having any of various hues and has high heat resistance, long life, high luminance, and high luminescent efficiency. In particular, the organic electroluminescent element can be prevented from attenuating in luminance with the progress of operation. [In the general formula (I), Ar1 to Ar6 each independently is (un)substituted aryl whose nucleus has 6-20 atoms; and L1 to L3 each independently is a connecting group represented by the following general formula (II). {In the general formula (II), R1 and R2 each independently is hydrogen, etc., provided that R1 and R2 may be bonded to each other to form an (un)saturated ring.}]
