Patent ID: 8859043

Claim:
A method of manufacturing an organic light-emitting display device using an organic layer deposition apparatus including a deposition source, a deposition source nozzle unit arranged at a side of the deposition source and including a plurality of deposition source nozzles, and a patterning slit sheet facing the deposition source nozzle unit and including a plurality of patterning slits and a plurality of spacers arranged on an outer surface of the patterning slit sheet and protruded from the outer surface of the patterning slit sheet, the plurality of spacers including a first spacer at a first side of a patterning slit of a pair of adjacent patterning slits of the plurality of patterning slits, and a second spacer at a second side of the patterning slit, the first and second spacers being spaced apart from each other and protruded farther from the outer surface than remaining portions of the patterning slit sheet between the first and second spacers, the method comprising: spacing a substrate that is a deposition target apart from the organic layer deposition apparatus by a distance, the substrate facing the outer surface of the patterning slit sheet, the patterning slit sheet being smaller than the substrate in at least one of a first direction or a second direction perpendicular to the first direction; discharging a deposition material from the deposition source nozzle unit and through the plurality of patterning slits; and depositing the deposition material onto the substrate while moving at least one of the organic layer deposition apparatus or the substrate relative to the other, wherein each of the plurality of spacers protrudes to a predetermined height from the patterning slit sheet toward the substrate.
