Abstract:
1. A method of manufacturing an organic light-emitting display device with a thin film deposition apparatus for forming a thin film on a substrate, the method comprising: arranging the substrate to be spaced from the thin film deposition apparatus; discharging a deposition material from a deposition source of the thin film deposition apparatus; passing the discharged deposition material through a deposition source nozzle unit of the thin film deposition apparatus, the deposition source nozzle unit being located at a side of the deposition source and comprising a plurality of deposition source nozzles arranged along a first direction; passing the discharged deposition material through a patterning slit sheet of the thin film deposition apparatus, the patterning slit sheet being located to face the deposition source nozzle unit and having a plurality of patterning slits, each of the plurality of patterning slits extending in the first direction and arranged along a second direction perpendicular to the first direction, the patterning slit sheet being supported by a plurality of supporting portions; and depositing the discharged deposition material from the patterning slit sheet onto the substrate, wherein the thin film deposition apparatus is configured to perform deposition while the thin film deposition apparatus or the substrate is moved relative to the other, and each of the plurality of supporting portions is not aligned in the second direction with any of the plurality of supporting portions which crosses adjacent ones of the plurality of patterning slits in the second direction, wherein at least one of the plurality of supporting portions crosses two or more neighboring patterning slits so as to support the patterning slit sheet, wherein the plurality of supporting portions divide the patterning slit into two or more regions, wherein the regions formed by one of the plurality of supporting portions have sizes different from the regions formed by an adjacent one of the plurality of supporting portions along the second direction.
