Abstract
This invention relates to an organic electroluminescent element (organic EL element) utilizing phosphorescence which shows improved luminous efficiency and driving stability and has a simple structure. The organic EL element comprises an anode, organic layers containing a hole-transporting layer, a light-emitting layer, and an electron-transporting layer, and a cathode piled one upon another on a substrate with the hole-transporting layer disposed between the light-emitting layer and the anode and the electron-transporting layer disposed between the light-emitting layer and the cathode. The light-emitting layer contains a compound represented by the following general formula (I) as a guest material and an organic metal complex containing at least one metal selected from ruthenium, rhodium, palladium, silver, rhenium, osmium, iridium, platinum, and gold as a guest material; in general formula (I), R.sub.1-R.sub.6 are independently hydrogen atoms, alkyl groups, aralkyl groups, alkenyl groups, cyano groups, alkoxy groups, aromatic hydrocarbon groups, or aromatic heterocyclic groups.
