Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a method of manufacturing an OLED by means of a solution method (solution processing method).SOLUTION: A method of manufacturing an OLED includes a step of depositing an organic layer containing a mixture of an organic electron acceptor and an organic electron donor and forming a layer that is insoluble to a nonpolar solvent. A device including the organic layer maintains good luminous efficiency, exhibits improved life, and may have a lower operating voltage.SELECTED DRAWING: Figure 3 【課題】溶液法（溶液加工法）によるＯＬＥＤの製造方法を提供する。【解決手段】この方法には、有機電子受容体及び有機電子供与体の混合物を含む有機層を堆積させて、非極性溶媒に不溶性である層を形成させる工程が含まれる。その有機層を含むデバイスは、良好な発光効率を維持しているとともに、向上した寿命を示し、且つより低い作動電圧を有しうる。【選択図】図３
