    • An organic electroluminescence (EL) device in which an organic thin film layer having a plurality of layers can be formed using any desired materials for an organic EL device in a simple and convenient production step, i.e., in accordance with a wet process, and which exhibits a great efficiency of light emission and has a long lifetime, a process for producing the device and an organic solution for an organic EL device realizing the process are provided. The device comprises at least one organic thin film layer in a plurality of layers containing at least a light emitting layer and sandwiched between a cathode and an anode those composing the organic electroluminescence device, wherein the organic thin film layer is formed in accordance with a wet process using a mixed solvent comprising a good solvent and a poor solvent. The process is a wet process using the mixed solvent. The organic solution is obtained by dissolving materials for an organic EL device forming the organic thin film layer into a mixed solvent comprising a good solvent and a poor solvent.
    • 在有机电致发光(EL)器件中,其中可以使用任何所需的有机EL器件材料在简单且方便的生产步骤中,即根据湿法制备具有多层的有机薄膜层,即根据湿法, 表现出很大的发光效率并且寿命长,提供了用于生产该装置的方法和实现该方法的有机EL器件的有机溶液。 该器件包括至少包含至少包含发光层并且构成有机电致发光器件的阴极和阳极之间的有机薄膜层,其中有机薄膜层根据湿气形成 使用包含良溶剂和不良溶剂的混合溶剂的方法。 该方法是使用混合溶剂的湿法。 通过将形成有机薄膜层的有机EL器件的材料溶解在包含良溶剂和不良溶剂的混合溶剂中来获得有机溶液。
