Abstract: A method of manufacturing a display device includes preparing a spraying device including a plurality of nozzles, dividing a discharge amount value range between a first reference discharge amount value and a second reference discharge amount value into k areas (k is a natural number), generating nozzle sets by combining n nozzles (n is a natural number) among m nozzles (m is a natural number, m≥n) for each of a plurality of nozzle groups, where the nozzle sets have a same discharge amount value as one another or different discharge amount values from one another, and each of the plurality of nozzle groups is defined by the m nozzles among the plurality of nozzles, and deriving an active nozzle group in which the nozzle sets are distributed in a preset manner in the k areas from the plurality of nozzle groups.
