Abstract
A method of manufacturing a deposition mask includes preparing a mask-target substrate which has one surface on which a sacrificed layer pattern is formed and comprises a cover area covered by the sacrificed layer pattern and a plurality of exposed areas exposed by the sacrificed layer pattern; forming holes in the exposed areas of the mask-target substrate by emitting laser toward the mask-target substrate; and removing the sacrificed layer pattern, wherein the sacrificed layer pattern has a higher reflectance with respect to the laser than a reflectance of the mask-target substrate.
