ORGANIC LAYER DEPOSITION ASSEMBLY, APPARATUS FOR ORGANIC LAYER DEPOSITION COMPRISING THE SAME, AND METHOD FOR MANUFACTURING OF ORGANIC LIGHT EMITTING DISPLAY APPARATUS USING THE SAME

摘要

An embodiment of the present invention discloses an organic layer deposition assembly for depositing a deposition material on a substrate. The organic layer deposition assembly includes: a deposition source which discharges the deposition material; a deposition nozzle unit which is placed on one side of the deposition source and comprises multiple deposition nozzles; and a patterning slit sheet which is placed opposite to the deposition nozzle unit and has multiple patterning slits. The substrate is formed so that the substrate is separated from the organic layer deposition assembly by a predetermined distance, and capable of relatively moving with respect to the organic layer deposition assembly. The deposition material discharged from the deposition source passes through the patterning slit sheet and is deposited on the substrate, forming a pattern on the substrate. The patterning slits have multiple openings through which the deposition material passes and ribs formed between the openings. The widths of the ribs are in a range of 0.6 to 0.7 mm.
