Claim Text:
1. A method of manufacturing an organic light-emitting display apparatus 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, a patterning slit sheet facing the deposition source nozzle unit and including a plurality of patterning slits, a blocking member, and a heating member on the blocking member, the method comprising; spacing a substrate which constitutes a target on which the deposition material is to be deposited apart from the organic layer deposition apparatus by a predetermined distance, the blocking member being between the substrate and the deposition source and blocking at least a portion of the substrate, 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; heating the blocking member using the heating member; discharging a deposition material from the organic layer deposition apparatus; 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 the deposition material is patterned on the substrate by the patterning slit sheet in a pattern in which the deposition material is deposited at first regions on the substrate corresponding to the pattern slits and is not deposited at second regions on the substrate adjacent the first regions.
