Claim:
1. A method of manufacturing an organic light-emitting display device, the method comprising: providing a thin film deposition apparatus; positioning a substrate such that the substrate is spaced apart from the thin film deposition apparatus; and depositing a deposition material onto the substrate by discharging the deposition material from the thin film deposition apparatus onto the substrate while moving one of the thin film deposition apparatus or the substrate relative to the other along a moving direction, wherein the depositing of the deposition material discharged from the thin film deposition apparatus onto the substrate comprises: depositing the deposition material through a plurality of patterning slits onto the substrate to form a plurality of sub-pixels, each of which corresponds to one of the plurality of patterning slits, wherein the plurality of patterning slits comprise a first patterning slit through which the deposition material passes for forming a first one of the plurality of sub-pixels, a second patterning slit through which the deposition material passes for forming a second one of the plurality of sub-pixels, and a third patterning slit through which the deposition material passes for forming a third one of the plurality of sub-pixels, wherein the first patterning slit has a first length extending along the moving direction, and the second patterning slit has a second length extending along the moving direction and substantially different from the first length, and wherein the first, second and third patterning slits are arranged to be spaced apart from each other.
