Display apparatus and, apparatus and method of manufacturing the same

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

• a chamber;
• a display substrate of the display apparatus arranged in the chamber, the display substrate comprising a first deposition area, and a second deposition area;
• a source portion arranged in the chamber and configured to supply a deposition material into the chamber;
• a first mask configured to be arranged in the chamber and comprising a first opening, through which the deposition material is configured to pass,
• wherein the first mask comprises a first protrusion protruding towards an inner portion of the first opening and configured to block the deposition material,
• wherein a portion of an inner surface of the first opening adjacent to the first protrusion has a concavo-convex shape comprising a plurality of protrusions and a plurality of recesses alternately arranged, a largest protrusion of the protrusions having a width that is twice a thickness of the first mask or less;
• and
• a second mask configured to be selectively arranged in the chamber to be replaceable with the first mask, the second mask comprising a second opening, through which the deposition material is configured to pass,
• wherein the second mask comprises a second protrusion protruding towards an inner portion of the second opening and configured to block the deposition material,
• wherein a portion of an inner surface of the second opening adjacent to the second protrusion has the concavo-convex shape comprising a plurality of protrusions and a plurality of recesses alternately arranged, a largest protrusion of the protrusions of the second mask having a width that is twice a thickness of the second mask or less,
• wherein the deposition material is configured to pass through the first opening to be deposited on a part of the display substrate to form the first deposition area and is configured to pass through the second opening to be deposited on a different part of the display substrate to form the second deposition area and different from the first deposition area,
• wherein the first deposition area and the second deposition area are connected to each other to form one display area on the display substrate, and
• wherein the first deposition area and the second deposition area at least partially overlap with each other.
