1. A method of manufacturing a display device, the method comprising:
preparing a spraying device including a plurality of nozzle heads, wherein each of the plurality of nozzle heads includes a plurality of nozzles;
dividing a discharge amount value range of each of the plurality of nozzle heads between a first reference discharge amount value and a second reference discharge amount value into k sub-ranges, wherein the second reference discharge amount value is greater than the first reference discharge amount value, and k is a natural number greater than or equal to 2;
generating nozzle sets by combining n nozzles among m nozzles for each of a plurality of nozzle groups, wherein n is a natural number greater than or equal to 2, and m is a natural number greater than or equal to n, wherein 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 to be activated from the plurality of nozzle groups, wherein the nozzle sets in the active nozzle group are distributed in a preset manner in the k sub-ranges.
