Abstract
A deposition mask apparatus includes a frame, a deposition mask, and an alignment mask. The alignment mask has two first alignment mask holes located at positions different from each other in the second direction and overlapping the frame. A first weld joining the frame with the alignment mask is located in an outer side of the alignment mask in the second direction with respect to a corresponding one of the first alignment mask holes. A second weld joining the frame with the alignment mask is located in an inner side of the alignment mask in the second direction with respect to a corresponding one of the first alignment mask holes.
Claims15
A deposition mask apparatus comprising:
- a frame having a first frame face, a second frame face located on an opposite side to the first frame face, and a frame opening extending through from the first frame face to the second frame face;
- a deposition mask joined to the first frame face and having a plurality of through-holes overlapping the frame opening in plan view;
- and
- an alignment mask joined to the first frame face and arranged side by side with the deposition mask in a first direction, wherein
- the alignment mask has two first alignment mask holes located at positions different from each other in a second direction orthogonal to the first direction and overlapping the frame,
- a first weld joining the frame with the alignment mask is located in an outer side of the alignment mask in the second direction with respect to each of the first alignment mask holes,
- a second weld joining the frame with the alignment mask is located in an inner side of the alignment mask in the second direction with respect to each of the first alignment mask holes,
- wherein the alignment mask has two second alignment mask holes located at positions different from each other in the second direction and overlapping the frame,
- wherein the second alignment mask holes are located between one of the second welds and the other one of the second welds in the second direction,
- wherein a third weld joining the frame with the alignment mask is located in an outer side of the alignment mask in the second direction with respect to each of the second alignment mask holes, and
- wherein a fourth weld joining the frame with the alignment mask is located in an inner side of the alignment mask in the second direction with respect to each of the second alignment mask holes.
