Mask assembly manufacturing apparatus and mask assembly manufacturing method using the same

A mask assembly manufacturing apparatus for manufacturing a mask assembly comprising:

• a frame through which an opening is defined and a support bar disposed above the frame, the mask assembly manufacturing apparatus comprising:
• a stage on which the frame is placed;
• an alignment unit disposed above the stage, wherein the alignment unit comprises a plurality of magnetic units;
• and
• a fixing unit disposed between the stage and the alignment unit, wherein the fixing unit comprises a first sub-fixing unit which fixes one end of the support bar and a second sub-fixing unit which fixes another end of the support bar and spaced apart from the first sub-fixing unit in a first direction;
• wherein the plurality of magnetic units comprises:
• a plurality of first magnetic units disposed above the support bar;
• and
• a plurality of second magnetic units disposed above the support bar, spaced apart from the first magnetic units in a second direction perpendicular to the first direction, wherein each of the second magnetic units is arranged such that a magnetic pole thereof faces an opposite magnetic pole of a corresponding first magnetic unit;
• where the plurality of first magnetic units and second magnetic units are each operative to exert a magnetic force on the support bar to prevent it from sagging.
