Abstract:
1. A method for fabricating an organic light-emitting layer as a functional-film, comprising: checking ejection/non-ejection states of a plurality nozzles in an ink jet head; and ejecting droplets of functional liquid from the plurality of nozzles to an ejection area during a single scanning of the ink jet head, the plurality of nozzles being arranged in rows with a predetermined pitch, and the ejection area being defined by being sandwiched between two or more parallel line-shaped banks, and being surrounded by bounded areas having a liquid repellent property, wherein, row areas defined by the line-shaped banks include a plurality of pixel areas disposed at constant intervals, said checking ejection/non-ejection states includes detecting at least one non-ejectable nozzle out of the plurality of nozzles, and said ejecting droplets of the functional liquid includes increasing the amount of droplets of the functional liquid ejected from an ejectable nozzle near the at least one non-ejectable nozzle relative to the amount of droplets of the liquid ejected from the ejectable nozzle when there is no non-ejectable nozzle so as to apply a coating to the ejection area, said increasing the amount of droplets of the functional liquid corresponding to the number of non-ejectable nozzles detected, and wherein the at least one non-ejectable nozzle includes a plurality of non-ejectable nozzles and the ejectable nozzle is an ejectable nozzle of a plurality of ejectable nozzles, and the ejection frequency at which the plurality of ejectable nozzles apply a coating of the functional liquid for complementing for the non-ejectable nozzles is equal to or more than twice the ejection frequency before the complementing.
