PROBLEM TO BE SOLVED: To realize an organic EL element which enables to achieve reliability of thermal stability and the like and high efficiency in the high brightness region at the same time by doping a triplet luminous material in an organic host material, particularly, in a non-conjugated unsaturated polymer. SOLUTION: The organic EL element comprises a hole injecting electrode, an electron injecting electrode and a luminous layer composed of an organic host material and a dopant disposed between these electrodes. The above organic material is made of a non-conjugated unsaturated polymer material and the above dopant is made of an organic metal complex capable of phosphorescence from a triplet state and contains at least a metal ion belonging to the VII family of the Mendeleyev periodic table. |
