    摘要： An object of the present invention is to provide an organic EL element which has a shorter maximum luminescent wavelength, a long luminous lifespan, a low driving voltage, a small time-dependent change in driving voltage, and a small change in external extraction quantum efficiency even when being used at a high temperature. In addition, an object of the present invention is to provide a lighting device and a display device including the organic EL element.The organic EL element of the present invention is an organic EL element including: at least one luminous layer sandwiched between a positive electrode and a negative electrode, wherein the luminous layer contains at least one kind of phosphorescent organometallic complex having a structure represented by the following Formula (1):

    摘要： A resin composition includes a resin or a resin precursor, and a nitrogen-containing aromatic heterocyclic compound. The nitrogen-containing aromatic heterocyclic compound has a structure represented by the following general formula (1), the following general formula (6) or the following general formula (7):




    In the general formula (1), A1 and A2 each represent a 6-membered nitrogen-containing aromatic heterocyclic ring together with a nitrogen atom, and the 6-membered nitrogen-containing aromatic heterocyclic ring optionally forms a fused ring; and L represents a single bond, or a linking group derived from an aromatic hydrocarbon ring, an aromatic heterocyclic ring, or an alkyl group. The resin composition includes the nitrogen-containing aromatic heterocyclic compound in a range from 0.10 to 30% by mass relative to the resin or the resin precursor.
