The present disclosures provide a deposition mask and a method of manufacturing the same. The disclosed deposition mask may include: a deposition portion including a plurality of deposition patterns; and a boundary portion surrounding the deposition portion and including a first region and a second region extending from the first region. The boundary portion may have a thickness thicker than that of the deposition portion. Through this, it is possible to prevent a thermal deformation of the mask which may occur when the mask and mask frame are welded to each other.

Deposition mask and method of manufacturing the same

A mask for deposition and a manufacturing method thereof are disclosed in aspects of the present disclosure. The disclosed mask for deposition and the manufacturing method thereof include: a deposition part including a plurality of deposition patterns; a peripheral part configured to surround the outside of the deposition part; and at least one extending part provided at the boundary between the deposition part and the peripheral part, wherein the extending part has a thickness smaller than that of the peripheral part. Accordingly, it is possible to enhance the strength of the boundary portion between the peripheral part and the deposition part of the mask for deposition.
