Patent ID: 8859325

Claim:
A method of manufacturing an organic light-emitting display device using a thin film deposition apparatus, the method comprising: separating a thin film deposition assembly of the thin film deposition apparatus from a substrate that is fixedly supported by a chuck and performing deposition on the substrate while the thin film deposition assembly or the substrate fixedly supported by the chuck is moved relative to the other, wherein the thin film deposition assembly comprises a deposition source that discharges a deposition material, a deposition source nozzle unit disposed at a side of the deposition source and including a plurality of deposition source nozzles arranged in a first direction, a patterning slit sheet disposed opposite to the deposition source nozzle unit and including a plurality of patterning slits having different lengths arranged in the first direction, and a barrier plate assembly disposed between the deposition source nozzle unit and the patterning slit sheet in the first direction, and including a plurality of barrier plates that partition a space between the deposition source nozzle unit and the patterning slit sheet into a plurality of sub-deposition spaces.
