PROBLEM TO BE SOLVED: To solve the problem of causing a variation in a film shape and a variation in a film thickness in a printing area when stringiness of organic functional ink is caused between a printing plate and a substrate, since viscosity of the organic functional ink increases, when the organic functional ink peels from a printing plate, when the viscosity of the organic functional ink changes in a process of separating after contacting the printing plate and the substrate in printing of using the organic functional ink of adding a thickener, though adding the thickener to provide printable viscosity, since the printable viscosity cannot be provided by the organic functional ink of only dissolving or dispersing in a solvent, in a low molecular material for constituting an organic functional layer.SOLUTION: The problem is solved by reducing the viscosity of the organic functional ink in the printing, by imparting vibration to a plate cylinder, when forming an organic functional element by a printing method by using the organic functional ink. |
