1. A deposition mask assembly, comprising:
- a frame including a first opening portion and a second opening portion spaced apart from each other in a first direction;
a first split mask group including a plurality of first split masks arranged on the first opening portion in a second direction crossing the first direction; and
a second split mask group including a plurality of second split masks arranged on the second opening portion in the second direction,wherein a boundary between adjacent first split masks in the second direction and a boundary between adjacent second split masks in the second direction are at different positions.

9. A method of manufacturing a display device, the method comprising:
-
disposing a deposition mask assembly on a deposition source, the deposition mask assembly including; a frame including a first opening portion and a second opening portion spaced apart from each other in a first direction, a first split mask group including a plurality of first split masks arranged on the first opening portion in a second direction crossing the first direction, and a second split mask group including a plurality of second split masks arranged on the second opening portion in the second direction, wherein a boundary between adjacent first split masks in the second direction and a boundary between adjacent second split masks in the second direction are at different positions; and moving a substrate over the deposition mask assembly in the first direction, while discharging a deposition material toward the substrate, such that the substrate sequentially passes through the first split mask group and the second split mask group using the deposition source to form a pattern layer on a portion of the substrate, the portion of the substrate passing through the first split mask group and the second split mask group. - View Dependent Claims (10, 11, 12, 13, 14, 15, 16, 17, 18, 19)
