    摘要: PROBLEM TO BE SOLVED: To provide an organic EL element which can extract luminescence with extremely narrow spectrum width even under excitation of low energy density (current density).
    SOLUTION: An organic electroluminescence element comprises a substrate, a positive electrode layer, an organic layer including at least one organic material and a negative electrode layer. The main light extracting direction is in the parallel direction against the surface of the substrate. One of the cut-off wavelengths of the transverse electric modes of an optical waveguide that has an organic layer constituted by the element as a part of its core is included in the wavelength band of full width at half maximum of the fluorescence spectrum of one of the organic materials included in the organic layer.
