Abstract:
1. A method of manufacturing an organic light-emitting display device by using a thin film deposition apparatus for forming a thin film on a substrate, the method comprising: 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; passing the discharged deposition material through a patterning slit sheet of the thin film deposition apparatus, the patterning slit sheet being disposed opposite to the deposition source nozzle unit and having a plurality of patterning slits, each of the plurality of patterning slits having a length in a first direction and a width in a second direction perpendicular to the first direction, the length of each patterning slit being larger than its width, the plurality of patterning slits being arranged in the second direction, and the length of a patterning slit located at one portion of the patterning slit sheet being different from the length of a patterning slit located at another portion of the patterning slit sheet, the patterning slit sheet having a length in the first direction smaller than a length of the substrate in the first direction, and the patterning slit sheet having a width in the second direction corresponding to a width of the substrate in the second direction; arranging the substrate a predetermined distance from and directly adjacent to the patterning slit sheet; and depositing the discharged deposition material from the patterning slit sheet onto the substrate, the patterning slit sheet providing a plurality of lines of the discharged deposition material along the first direction on the substrate, the plurality of lines of the discharged material being discrete from each other, and the thin film deposition apparatus performing deposition while the thin film deposition apparatus or the substrate is moved relative to each other in the first direction, wherein the deposition source, the deposition source nozzle unit, and the patterning slit sheet are stationary relative to one another during the deposition.
