    Abstract: A mask assembly includes a mask frame through which a plurality of openings is defined and a plurality of cell masks disposed to respectively correspond to the cell openings. Each of the cell masks includes a mask main body substantially parallel to a plane defined by a first direction and a second direction crossing the first direction, where a plurality of holes is defined through the mask main body, a bonding portion disposed along an edge of the mask main body, and a tensile portion extending from the bonding portion and disposed spaced apart from the mask main body. The tensile portion includes first tensile portions spaced apart from each other in the first direction and disposed at opposite sides of the mask main body and second tensile portions spaced apart from each other in the second direction and disposed at opposite sides of the mask main body.

    CPC classification number: B05B12/24

    Abstract: A mask assembly includes a frame including first to fourth lateral parts connected to define a frame opening, an open sheet including a body part in which sheet openings arranged in a first direction and a second direction are defined to overlap the frame opening and a connecting part protruding from the body part and at least partially overlapping the frame, and masks, each including a deposition part having deposition openings defined therein and coupling parts that protrude from the deposition part and that are spaced apart from each other with the deposition part therebetween. The connecting part includes a first connecting part and a second connecting part that overlap the frame and a third connecting part and a fourth connecting part that at least partially overlap the frame.
