According to one or more embodiments, a mask assembly includes a mask frame including an opening and a portion surrounding the opening, and a mask arranged on the mask frame and including a first region and a second region, and a deposition material is passable through the first region corresponding to the opening, and the second region is around the first region, and the first region includes deposition openings, and the second region includes dummy openings, at least some of the dummy openings including centers arranged to deviate from a straight line connecting centers of the deposition openings, and a width of each of the deposition openings is the same as a width of each of the dummy openings.

Mask assembly, apparatus for manufacturing display device, and method of manufacturing display device

Provided are a method of manufacturing a mask that has a high precision configured to minimize a shadow effect, and a method of manufacturing a display device. The method of manufacturing a mask includes: tensioning a mask sheet; bonding the mask sheet that is tensioned to a mask frame; and forming an opening in the mask sheet by irradiating laser light on the mask sheet such that an inner wall of the opening has a slope with respect to a surface of the mask sheet.

Method of manufacturing mask and method of manufacturing display device

Provided are a display device, a mask assembly, and an apparatus and a method for manufacturing the display device. The mask assembly includes: a mask frame; at least two mask sheets installed on the mask frame, each of the mask sheets including a plurality of openings; and at least two thin shielding plates installed on the mask frame such that the thin shielding plates are spaced apart from each other and shield a portion of the plurality of openings of each mask sheet, wherein one of the mask sheets and the thin shielding plates includes a shielding portion between the thin shielding plates spaced apart from each other, the shielding portion selectively blocking at least portions of the openings so as to form a deposition region having a shape other than a rectangle or a square.

Mask assembly, apparatus and method of manufacturing display device using the same, and display device

A mask assembly for thin film deposition includes: a mask frame including an opening, the mask frame disposed surrounding the opening; and a mask unit including: first masks mounted on the mask frame, the first masks extending in a first direction; a second mask disposed on the first masks, the second mask including: one open hole; and at least one foreign substance discharge hole; and a third mask disposed on the second mask, the third mask extending in a second direction and including deposition holes, wherein the second direction crosses the first direction, and wherein a substrate is disposed on the third mask.
