摘要：
An organic electroluminescent (EL) device comprised of a starburst aromatic amine compound represented by the formula ##STR1## wherein N is nitrogen; A.sup.1 to A.sup.3 each individually represent biaryl; R.sub.a, R.sub.b, and R.sub.c represent independently one of the functional groups of the following formulae ##STR2## wherein N is nitrogen; each Ar.sup.1 and Ar.sup.2 are aryl; R.sub.1 to R.sub.8 are substituents independently selected from the group consisting of hydrogen, halogen, hydrocarbon, and alkoxy; and X represents oxygen, sulfur, or an alkylene.
