A mask assembly includes: a mask frame having a plurality of sides including a first side extending in a first direction, and an opening area defined by the plurality of sides; a gap portion recessed in the first side in a second direction crossing the first direction; a mask sheet covering the opening area; and a gap adjustment portion tensile-welded to the mask frame across the gap portion.

Mask assembly and method of manufacturing display apparatus

A mask assembly including a mask frame including an opening; and a mask arranged on the mask frame and including a deposition region and a non-opening region arranged around the deposition region, the deposition region facing the opening to transmit a deposition material. A width of the non-opening region in a lengthwise direction of the mask is about 200 μm to about 500 μm.

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

Provided is a mask assembly including a mask frame including an opening; and a mask arranged on the mask frame and including a deposition region and a non-opening region arranged around the deposition region, the deposition region facing the opening to transmit a deposition material. A width of the non-opening region in a lengthwise direction of the mask is about 200 &#x3bc;m to about 500 &#x3bc;m.

A method of manufacturing a mask frame assembly includes: welding fixing ends of a long-side support bar on a frame; and fixing a mask having a pattern area to be divided by the long-side support bar, on the frame, wherein the welding of the fixing ends of the long-side support bar on the frame includes forming welds asymmetrically with respect to a longitudinal central axis of the fixing ends.

Mask frame assembly and method of manufacturing the same

A mask assembly may include a frame, first sticks, and masks. The first sticks may extend in a first direction and may be arranged in a second direction. The plurality of masks may be disposed on the frame and the first sticks. The plurality of masks may extend in the second direction and may be arranged in the first direction. Each of the first sticks may have a first edge and a second edge, which are opposite to each other in the second direction. When viewed in a plan view defined by the first and second directions, the first and second edges of an outermost stick of the first sticks may have different shapes, and linear lengths of the first and second edges of the outermost stick may be substantially equal to each other, where the linear lengths are lengths of the first and second edges in a straight state.
