Abstract
Each of two divided masks next to each other in a second direction includes an overlapping region where two unit mask members partially overlap each other in a planar view, and a pitch in the second direction between openings on a plurality of divided masks each including the overlapping region is the same as a pitch in the second direction between the opening on each of a plurality of divided masks.

A vapor deposition mask comprising:
- a mask frame having frame-shape including an opening;
- and
- a plurality of unit mask members, each unit mask member including a plurality of openings and having a length in a first direction longer than a length in second direction perpendicular to the first direction, each of the plurality of unit mask members being fixed to the mask frame,
- wherein in the plurality of unit mask members, each of two unit mask members next to each other in the second direction includes an overlapping region where the two unit mask members partially overlap each other in a planar view,
- a pitch in the second direction between the plurality of openings on the plurality of unit mask members each including the overlapping region is the same as a pitch in the second direction between the plurality of openings in a region other than the overlapping region in each of the plurality of unit mask members,
- each of the plurality of unit mask members includes a first end region and a second end region on both ends in the second direction,
- the first end region and the second end region are regions where the plurality of openings are not formed,
- a width of each of the first end region and the second end region in the second direction is equal to a distance in the second direction between two openings next to each other in the second direction among the plurality of openings, and
- the overlapping region is a region where the first end region of one unit mask member of two unit mask members next to each other in the second direction among the plurality of unit mask members and a plurality of openings next to the first end region and arranged along the first direction overlap, in a planar view, the second end region of the other unit mask member and a plurality of openings next to the second end region and arranged along the first direction.
