A mask assembly includes: a mask extended in a first direction and including a pattern region and in which an alignment adjustment pattern and a first welding part are formed, and a first deposition region in which upper openings are formed; and a mask frame extended in a second direction and including a first support portion and an edge portion overlapping the pattern region. The alignment adjustment pattern may have a shape in which at least a portion of the mask positioned in the pattern region is removed. Accordingly, the mask assembly may reduce the manufacturing cost of the mask assembly by using a relatively small number of masks. 마스크 조립체는 정렬 조정 패턴 및 제1 용접부가 형성된 패턴 영역 및 상부 개구들이 형성된 제1 증착 영역을 포함하고, 제1 방향으로 연장하는 마스크 및 제2 방향으로 연장하며 패턴 영역과 중첩하는 제1 지지부 및 테두리부를 포함하는 마스크 프레임을 포함하고, 정렬 조정 패턴은 패턴 영역에 위치하는 마스크의 적어도 일부가 제거된 형태를 가질 수 있다. 이에 따라, 마스크 조립체는 상대적으로 적은 개수의 마스크를 사용함으로써 마스크 조립체의 제조 비용을 줄일 수 있다.
