摘要：
Described is an organic electroluminescent device material which comprises a coumarin derivative represented by the following formula (1): ##STR1## wherein R.sub.1 to R.sub.4 each independently represents a hydrogen atom, a halogen atom or a substituted or unsubstituted alkyl, alkoxy, thioalkyl, aryloxy, arylthio, carbocyclic aromatic or heterocyclic aromatic group; and an organic electroluminescent device fabricated using the material. According to the present invention, a red-emitting material with high brightness and high luminous efficiency indispensable for full color display can be provided.
