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.

Deposition mask and method of manufacturing the deposition mask

A deposition mask including a resin film including first holes, a non-resin layer disposed on the resin film and including second holes corresponding to the first holes, and a protective layer disposed on the non-resin layer and including third holes corresponding to the first holes, wherein the protective layer includes a first portion disposed on a top surface of the non-resin layer, and a second portion covering a side surface of the second holes of the non-resin layer.

Mask for deposition

A deposition mask for making a display device, the deposition mask includes: a frame including a first opening; a first member disposed above the first opening of the frame and including a first portion surrounding at least one second opening and a second portion disposed in the second opening and physically separated from the first portion; and a second member disposed on the first member and including a first connecting portion connected to the frame and a second mesh portion overlapping the second portion.
