摘要：
An object of the present invention is to provide an organic EL element having high light extraction efficiency and to provide a lighting device and a display device provided using the organic EL element. The organic EL element 1 includes: a transparent substrate 2 having a refractive index of 1.8 or more; a stacked body 6 that is provided on the substrate 2 and includes at least one pair of electrodes 3 and 4 and an organic light-emitting layer 5 located between the pair of electrodes 3 and 4; and a porous light-scattering body 2a that is provided on a surface of the substrate 2, the surface being opposite to the stacked body 6.
