Claim:
A liquid material arrangement method for arranging a prescribed quantity of liquid material in each of a plurality of units of a prescribed region on a substrate, the liquid material arrangement method comprising: performing a first pattern generating step for generating a first dot pattern in which a first prescribed number of dots is set according to each of the units of the prescribed region on the substrate, the first prescribed number corresponding to a quantity of liquid material that is larger than the prescribed quantity of liquid material; performing a discharge information acquiring step for acquiring discharge information of each of a plurality of nozzles corresponding to the first prescribed number of dots in each of the units of the prescribed region, the discharge information including a presence of discharge anomaly in each of the nozzles and an accuracy of an arrangement position of the liquid material discharged from each of the nozzles; performing a dot deleting step for deleting a second prescribed number of dots including at least one prohibited dot with priority from the first prescribed number of dots to generate a second dot pattern respectively for each of the units of the prescribed region on the substrate, the second prescribed number being set such that a number of dots remaining in the second dot pattern corresponds to the prescribed quantity of liquid material with the first prescribed number and the second prescribed number being constant for each of the units of the prescribed region, the prohibited dot being determined based on the discharge information of each of the nozzles determined in advance; and performing a liquid material arranging step for arranging the liquid material in each of the units of the prescribed region on the substrate by causing the nozzles and the substrate to scan in relative manner and discharging the liquid material from the nozzles based on the second dot pattern.
