Patent number: 6626717Abstract: In a manufacturing step for forming an organic EL element, the organic EL element is provided so as to have an anode and a cathode with a luminescent layer having an organic luminescent material interposed therebetween. Then, an aging treatment is performed. In the aging treatment, a curve of change in luminance with time is measured in driving the organic EL element at constant current. Then, the curve of change in luminance with time is divided into a component having a slowest luminance age-deterioration rate and other components by analyzing the curve and forming a fitting curve having a plurality of members that is fitted to the curve of change in luminance with time. Moreover, the aging treatment is conducted until a luminance of the element becomes approximately equal to an initial value A1 of the component having a slowest luminance age-deterioration rate.Type: GrantFiled: December 21, 2001Date of Patent: September 30, 2003Assignee: Denso CorporationInventors: Koichi Miyashita, Takayoshi Kuriyama, Masahiko Ishii
