Abstract
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.
