PROBLEM TO BE SOLVED: To provide an organic electric field light-emitting element in which color purity is improved by improving element constitution of the organic electric field light-emitting element. SOLUTION: The organic electric field light-emitting element has a pair of electrodes and a layer composed of an organic substance of at least one layer or more sandwiched between them, and a light-emitting color adjusting layer is inserted between the organic layer and the electrode. By this, to improve the color purity becomes possible. Further, it is also enabled that the light- emitting color adjusting layer is made to have an absorbance in wavelength regions in addition to the desired emitting wavelength region, and by this, suppression of deteriorating the color purity becomes possible by absorbing unnecessary light emissions.
