<p>An organic electroluminescent device of the type comprises an organic layer 5, 5a or 5b having a luminescent region and provided between an anode 2 and a cathode 3. The organic layer contains a distyryl compound represented by the following general formula (1). <H0> Chemical Formula 1 </H0> <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> in which R<9>, R<10>, R<11>, R<12> and R<13> may be the same or different and, respectively, represent a hydrogen atom provided that at least one of them is a saturated or unsaturated alkoxyl group or an alkyl group, and R<5>, R<6>, R<7> and R<8> may be the same or different and, respectively, represent a hydrogen atom provided that at least one of them represents a cyano group, a nitro group or a halogen atom. <IMAGE></p> |
