An organic electroluminescent device comprises an organic layer which has a luminescent region and which contains a distyryl compound represented by the following general formula (1). Chemical formula 10 <CHEM> wherein R<1>, R<2>, R<3> and R<4> are, respectively, groups which may be the same or different and independently represent an aryl group of the following general formula (2), <CHEM> wherein R<19>, R<20>, R<21>, R<22> and R<23> are, respectively, groups which may be the same or different and represent a hydrogen atom provided that at least one of them a saturated or unsaturated alkoxyl group, an alkyl group, an amino group or an alkylamino group, and R<5>, R<6>, R<7>, R<8>, R<9>, R<10>, R<11>, R<12>, R<13>, R<14>, R<15>, R<16>, R<17> and R<18> are groups which may be the same or different provided that at least one of them represents a cyano group, a nitro group or a halogen atom. <IMAGE> |
