Abstract:
1. A method of manufacturing an organic light-emitting diode (OLED) display, the method comprising: providing a substrate; discharging a deposition material from a deposition source; passing the discharged deposition material through a deposition source nozzle unit, wherein the deposition source nozzle unit comprises a plurality of deposition source nozzles arranged in a first direction; and depositing the discharged deposition material, which has passed through the deposition source nozzle unit, onto the substrate through a patterning slit sheet, wherein the patterning slit sheet is closer to the substrate than the deposition source nozzle unit, and wherein the patterning slit sheet comprises i) a base sheet, in which a plurality of sub-patterning slits are arranged in a second direction crossing the first direction, the base sheet having a plurality of patterning ribs between the plurality of sub-patterning slits, and ii) a plurality of patterning bars on the plurality of patterning ribs, each of the plurality of patterning bars partially blocking each of the adjacent sub-patterning slits, all the plurality of patterning bars being substantially parallel to each other, wherein the depositing is performed while moving the substrate relative to the patterning slit sheet in the first direction.
