Method of manufacturing organic light-emitting display apparatus

A method of manufacturing an organic light-emitting apparatus, the method comprises:

• transporting a moving unit to which a substrate is fixed to a chamber by using a first transport unit;
• forming a layer by depositing a deposition material discharged from a deposition assembly while relatively transporting the substrate with respect to the deposition assembly by using the first transport unit while the deposition assembly and the substrate disposed in the chamber are distanced apart at a set interval;
• and
• returning the moving unit from which the substrate is separated back by using a second transport unit configured to penetrate the chamber;
• wherein the deposition assembly comprises a deposition source configured to evaporate the deposition material, a nozzle unit disposed to face toward the first transport unit and having a deposition source nozzle, and a patterning slit sheet facing the deposition nozzle unit and having a sheet, a frame attached to the sheet, and a prop unit attached to the frame,
• wherein the sheet comprises a slit area, a first dummy slit area, a second dummy slit area, and a binding area, wherein the slit area has a plurality of patterning slits that are extended along a first direction and arranged along a second direction crossing the first direction, wherein the first dummy slit area is outside the slit area in the second direction and has a plurality of dummy slits that are extended along the first direction and arranged along the second direction, wherein the second dummy slit area is outside the slit area in an opposite direction of the second direction and has a plurality of dummy slits that are extended along the first direction and arranged along the second direction, wherein the binding area surrounds the slit area, the first dummy slit area, and the second dummy slit area;
• wherein the forming of the layer comprises forming of a layer while the frame is attached to the binding area of the sheet, and the prop unit is configured to shield at least some of the plurality of the first dummy slit area and the second dummy slit area of the sheet.
