摘要： PROBLEM TO BE SOLVED: To provide a method capable of manufacturing an electronic device such as a large-sized organic EL panel and an organic thin-film transistor in which an ink-jet method of high material utilization efficiency is used for organic low molecule materials refined by distillation or sublimation, and which is high in throughput.
SOLUTION: Two kinds of solvents are mixed, optimum ink viscosity is secured, and amorphous films of the organic materials are formed by the ink-jet method selectively only on a recessed region partitioned by a barrier rib layer by increasing surface tension of ink and a dissolution limit of the organic materials in a drying process. A first solvent of the two is a first solvent medium of which a solubility is 0.5 wt% or more, and a second solvent is a second solvent medium of which a solubility is 0.1 wt% or less. It is desirable that the boiling point of the first solvent medium is higher than that of the second solvent medium, and by using this ink solvent series, generation of crystalline nuclei and coagulation can be suppressed, and a uniform amorphous thin film formation becomes possible because a ratio of the first solvent medium in the ink increases along with drying.
