ORGANIC ELECTROLUMINESCENCE ELEMENT, METHOD OF AGING SAME, AND METHOD AND DEVICE OF EVALUATING SAME

PROBLEM TO BE SOLVED: To provide an organic electroluminescent element which utilizes an evaluation method capable of easing highly accurate evaluation for a short time, and to provide a method of aging the organic electroluminescence element, as well as a method and a device for evaluating the electroluminescence element. SOLUTION: The method is used to evaluate an organic electroluminescence element. In the method, while changing a magnetic field to be applied to the organic electroluminescent element as a standard specimen, luminance or emission intensity of the organic electroluminescence element as the standard specimen is measured; while changing a magnetic field to be applied to the organic electroluminescent element as a measured object, luminance or emission intensity of the organic electroluminescent element as the object is measured; the measurement result of the organic electroluminescent element as a standard specimen, and that of the organic electroluminescence element as a measured object are subject to fitting; and then the history or remaining service life of the organic electroluminescence element is estimated as the measured object.
