Mask assembly, apparatus for manufacturing display device, and method of manufacturing display device

An apparatus for manufacturing a display device, the apparatus comprising:

• a mask assembly;
• and
• a deposition source facing the mask assembly and configured to spray a deposition material toward the mask assembly in a first direction,
• wherein the mask assembly comprises:
• a mask frame comprising a plurality of sides and an opening;
• a first support stick arranged on the mask frame to overlap the opening, the first support stick extending in a direction parallel to one of the plurality of sides of the mask frame;
• a mask sheet arranged on the first support stick, the mask sheet extending in a direction parallel to one of the plurality of sides of the mask frame;
• and
• a first waterproof membrane arranged on a surface of the first support stick facing the first direction.

A method of manufacturing a display device, the method comprising:

• arranging a mask assembly and a deposition source to face a substrate;
• aligning the mask assembly to the substrate;
• and
• depositing a deposition material on the substrate by spraying the deposition material from the deposition source toward the mask assembly in a first direction,
• wherein the mask assembly comprises:
• a mask frame comprising a plurality of sides and an opening;
• a first support stick arranged on the mask frame to overlap the opening, the first support stick extending in a direction parallel to one of the plurality of sides of the mask frame;
• a mask sheet arranged on the first support stick, the mask sheet extending in a direction parallel to one of the plurality of sides of the mask frame;
• and
• a first waterproof membrane arranged on a surface of the first support stick facing the first direction.
