Organic layer deposition apparatus and method of manufacturing organic light-emitting display apparatus using the same

An organic layer deposition apparatus, the apparatus comprising:

• a conveyer unit that includes
• a moving unit configured to move a substrate fixed thereto,
• a first conveyer unit configured to move the moving unit in a first direction during which an organic material is deposited on the substrate fixed to the moving unit, and
• a second conveyer unit configured to move the moving unit in a second direction opposite to the first direction after deposition is completed and the substrate is separated from the moving unit, and
• a deposition unit comprising one or more organic layer deposition assemblies configured to deposit an organic layer on a moving substrate, wherein each of the one or more organic layer deposition assemblies comprises:
• a deposition source configured to discharge a deposition material;
• and
• a patterning slit sheet disposed to face the deposition source,
• wherein the first conveyer unit and the second conveyer unit are configured to move through the deposition unit,
• wherein the patterning slit sheet comprises:
• a first fixing frame;
• a second fixing frame attached to the first fixing frame, said second fixing frame having at least one portion whose thickness is less than thicknesses of other portions;
• and
• a pattern sheet that is fixed to the second fixing frame to face the deposition source, and which has a plurality of pattern slits,
• wherein the deposition material discharged by the deposition source flows through the patterning slit sheet to form a pattern on the moving substrate.
