VAPOR DEPOSITION MASK AND MANUFACTURING METHOD OF VAPOR DEPOSITION MASK

摘要

The present invention provides a vapor deposition mask which can deposit a layer of a deposition material while maintaining high material usage efficiency. The vapor deposition mask comprises a metal sheet having a first surface, a second surface disposed on an opposite side of the first surface, and a penetration hole formed thereon to extend between the first surface and the second surface. A recess is formed on the first surface of the metal sheet to extend in a line. A hole is formed on the second surface of the metal sheet. The recess and the hole are connected, and the penetration hole penetrates the metal sheet by the recess and the hole.
