Abstract
A deposition mask includes a first area defining a clamping portion at ends of the deposition mask and to which a force is applied to extend the deposition mask in a length direction thereof, a recess area adjacent to the first area and defining a recess at the ends; and a pattern portion including a plurality of pattern holes through which a deposition material passes. Along the length direction, a plurality of first pattern portions are arranged in the first area and a plurality of second pattern portions arranged in the recess area. When the force is applied to the clamping portion, the deposition mask is extended in the length direction thereof and defines non-extended positions of the pattern portions, and for the non-extended positions of the first and second pattern portions, a first distance between adjacent first pattern portions is less than a second distance between adjacent second pattern portions.
