An organic EL element (Al) includes an anode () and a cathode () which are arranged opposite to each other, and an organic layer () intervening between the anode () and the cathode () and including a light emitting layer (). The cathode () is made of MgAg alloy and has a thickness of not more than 200 &#x212b;. Preferably, the thickness of the cathode () is in the range of 40 to 100 &#x212b;.

Organic el element, organic el display device, and process for producing organic el element

An organic electroluminescence device, includes a substrate; an anode layer; an organic layer including at least one organic material having a fluorescence spectrum; and a cathode layer, wherein the organic electroluminescence device has a primary light outgoing direction that is parallel to a surface of the substrate, wherein the organic electroluminescence device has an optical waveguide that includes a core layer formed by the anode layer and the organic layer, and a clad layer formed by the substrate and the cathode layer, and wherein the optical waveguide has cutoff wavelengths in a transverse electric mode any one of which is within a wavelength range of a full width at half maximum of the fluorescence spectrum of any one of the organic materials included in the organic layer.
