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):
