Abstract:
1. A method of manufacturing an organic light-emitting display device by using a thin film deposition apparatus comprising a thin film deposition assembly, the thin film deposition assembly comprising: a deposition source that comprises an opening and discharges a deposition material contained therein; a deposition source nozzle unit that is disposed at a side of the deposition source and comprises a plurality of deposition source nozzles arranged in a first direction; a patterning slit sheet that is disposed opposite to the deposition source nozzle unit and comprises a plurality of patterning slits arranged in the first direction; a plurality of barrier pipes that are disposed on a surface of the deposition source nozzle unit facing the patterning slit sheet or on a surface of the deposition source nozzle unit opposite to the patterning slit sheet, the plurality of barrier pipes respectively corresponding to the plurality of deposition source nozzles, and the method comprising: fixedly supporting a substrate by a chuck; spacing the substrate from the patterning slit sheet and adjacent to the patterning slit sheet so that no element is interposed between the substrate and the patterning slit sheet; depositing the deposition material on the substrate to form a thin film; and moving the thin film deposition assembly including the patterning slit sheet, or the substrate fixedly supported by the chuck relative to each other while depositing the deposition material on the substrate, wherein, in depositing the deposition material on the substrate, the deposition material is discharged from the deposition source and passed through the deposition source nozzle unit, the barrier pipes, and the patterning slit sheet.
