Claim:
1. A method of manufacturing an organic light-emitting device comprising a plurality of pixels using an organic solution spray apparatus, wherein each of the pixels comprises a plurality of sub-pixels having different colors from one another, the method comprising: preparing a substrate on which a plurality of sub-pixel regions is defined; generating a potential difference between a nozzle of the organic solution spray apparatus and at least one sub-pixel region among the plurality of sub-pixel regions; spraying an organic solution from the nozzle of the organic solution spray apparatus to the sub-pixel regions; and forming an organic material layer by selectively depositing the organic solution onto the at least one sub-pixel region among the plurality of sub-pixel regions; the generating the potential difference between the nozzle of the organic solution spray apparatus and the at least one sub-pixel region among the plurality of sub-pixel regions comprises applying a potential having a first polarity to a nozzle of the organic solution spray apparatus;
