Mask frame assembly, method of manufacturing the same, and method of manufacturing organic light-emitting display device

A method of manufacturing a mask frame assembly, the method comprising:

• forming a first through hole in a vicinity of a first deposition region of a first mask;
• forming a second through hole in a vicinity of a second deposition region of a second mask;
• forming a third through hole in a first portion of a supporting stick;
• forming a fourth through hole in a second portion of the supporting stick;
• aligning the first through hole with the third through hole;
• aligning the second through hole with the fourth through hole;
• inserting a fixing member in the aligned first and third through holes;
• and
• inserting the fixing member in the aligned second and fourth through holes,
• wherein the supporting stick couples the first mask and the second mask together via the fixing member.

A method of manufacturing an organic light-emitting display device comprising a first electrode facing a second electrode, and an organic film disposed on a substrate between the first electrode and the second electrode, the method comprising:

• forming the organic film and the second electrode using a mask frame assembly comprising:
• a frame comprising an opening portion;
• a first mask comprising ends connected to the frame, the first mask comprising:
• a first deposition region disposed in correspondence with the opening portion of the frame;
• and
• a first through hole disposed in a vicinity of the first deposition region;
• a second mask comprising ends connected to the frame, the second mask comprising:
• a second deposition region disposed in correspondence with the opening portion of the frame;
• and
• a second through hole disposed in a vicinity of the second deposition region;
• a supporting stick comprising:
• a first portion overlapping a portion of the first mask, the first portion comprising a third through hole overlapping the first through hole;
• and
• a second portion overlapping a portion of the second mask, the second portion comprising a fourth through hole overlapping the second through hole;
• and
• a fixing member extending into:
• the first through hole and the third through hole;
• and
• the second through hole and the fourth through hole.
