Document Type and Number:
Japanese Patent JP6341434
Kind Code:
B2
Abstract:
A deposition mask includes: a mask sheet formed by stacking a metal layer provided with a plurality of through holes on a film layer provided with a plurality of opening patterns, each through hole enclosing at least one of the opening patterns, and by dividing one surface of the mask sheet into a plurality of unit cells each including two or more of the opening patterns and two or more of the through holes; and a support member which is made of metal and has openings corresponding to the unit cells of the mask sheet, the support member supporting the mask sheet by being joined to the metal layer of the mask sheet to which no external tension is applied.
