In a droplet ejection control apparatus according to the invention, a judgment section judges, taking a dot position that is assigned by a predetermined nozzle (incorrect ejection position) as a reference, whether or not a printing state is such that a second proximity dot lands earlier than a first proximity dot. A changing section changes an ejection state, when the ejection state is judged to be such that the second proximity dot lands earlier than the first proximity dot, to another ejection state in which the first proximity dot lands earlier than the second proximity dot.

Forming functional layers including functional material in application regions by applying ink to the application regions then drying the ink, which contains the functional material, by causing nozzles to be scanned relative to the substrate along the row direction while, among the nozzles, only use-nozzles that are not selected as a defective nozzle eject the ink, the nozzles being arranged in the column direction over the substrate and including a nozzle selected in advance as a defective nozzle. Among the nozzles, when applying the ink, at least one reserve nozzle is present, a reserve nozzle being a nozzle that is not one of the use-nozzles, is not selected as the defective nozzle, passes over the application region, and does not eject the ink.
