ORGANIC ELECTROLUMINESCENT DEVICE, METHOD FOR MANUFACTURING SAME AND ORGANIC SOLUTION |
摘要 |
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.
