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 elementincludes: a transparent substratehaving a refractive index of 1.8 or more; a stacked bodythat is provided on the substrateand includes at least one pair of electrodesandand an organic light-emitting layerlocated between the pair of electrodesand; and a porous light-scattering bodythat is provided on a surface of the substrate, the surface being opposite to the stacked body

Organic electroluminescence element, lighting device, and display device

A composite emitting device including: a supporting substrate, a first emitting part comprising a first electrode, a luminescent medium, and a second electrode stacked in this order on the supporting substrate, and a second emitting part including a fluorescent film arranged in a direction different from the light-out coupling direction relative to the luminescent medium, the luminescent medium emitting light by applying a voltage between the first electrode and the second electrode in the first emitting part, and the fluorescent film of the second emitting part absorbing light emitted from the luminescent medium to emit light.

A transparent electrode composed of ITO(indium-tin oxide), an insulating layer composed of ZrSiN, an underlayer composed of MgS with a thickness of 100 to 300 nm, a light emitting layer composed of MgCaS, and an insulating layer composed of ZrSiN are formed in this order on a glass substrate. Electrodes composed of Al are formed on the insulating layer. The underlayer is formed by sputtering with the substrate temperature set to room temperature. The light emitting layer is formed by sputtering with the substrate temperature set to not lower than 100&#xb0; C.
