A mask including: a deposition pattern portion including a plurality of deposition holes that are configured to have deposition material pass therethrough; and a dummy pattern portion outside the deposition pattern portion, wherein the dummy pattern portion includes an auxetic structure having a negative Poisson's ratio.

Mask, mask assembly, and apparatus for manufacturing display apparatus

A display device includes: a substrate comprising a first display area and a second display area, the first display area comprising a transparent area and the second display area being arranged to surround at least a portion of the first display area; a first pixel in the first display area and comprising a first pixel electrode, a first intermediate layer, and a first opposite electrode; and a second pixel in the second display area and comprising a second pixel electrode, a second intermediate layer, and a second opposite electrode, wherein each of the first intermediate layer and the second intermediate layer comprises a first section having a portion where a thickness thereof is constant and a second section where the thickness thereof is variable.

Display device, mask assembly, method of manufacturing the mask assembly, apparatus for manufacturing the display device, and method of manufacturing the display device

A division mask includes a main body including at least one opening pattern, and a clamping portion at an edge of the main body, the clamping portion having an increasing width with respect to an increasing distance from the main body, and the clamping portion including a fan-out portion extending from the main body and including at least one dummy pattern, and at least one branch portion having a decreasing width with respect to an increasing distance from the fan-out portion.

Division mask with clamping portion

A method of manufacturing a division mask includes pulling opposite end portions of a mask member in a first direction to fasten the mask member to a fastening portion, forming a first pattern portion having a plurality of first openings on the fastened mask member, such that the first pattern portion has a longer length in the first direction toward a central portion of the first pattern portion, and cutting the opposite end portions of the mask member to detach the mask member from the fastening portion.

Method for fabricating division mask

A mask assembly includes a frame and a mask supported by the frame. The mask includes a plurality of deposition patterns. Each of the plurality of deposition patterns includes a first pattern portion disposed in an active area corresponding to a display area of a display substrate, a second pattern portion disposed in a dummy area corresponding to a non-display area of the display substrate, and a third pattern portion disposed in a dummy outer area also corresponding to the non-display area of the display substrate. The dummy area extends from the active area to the dummy outer area and the dummy outer area extends from the dummy area to an edge of each of the plurality of deposition patterns. The first pattern portion includes a plurality of first holes, the second pattern portion includes a plurality of second holes, and the third pattern portion includes a plurality of grooves.

Mask assembly for thin film deposition

A mask frame assembly includes a frame, and a mask tensioned on the frame in a first direction, the mask having a deposition pattern portion having a plurality of pattern holes therethrough, a deposition material being deposited on a substrate through the pattern holes, and a dummy portion extending from the deposition pattern portion in the first direction, the dummy portion having an increased thickness in a second direction as a distance from the deposition pattern portion in the first direction increases, the second direction being oriented along a normal to the mask.

Mask frame assembly, method of manufacturing the same, and method of manufacturing organic light-emitting display apparatus

A packaging apparatus is provided for packaging one or more deposition masks. The apparatus comprises a base comprising a first surface and a first recess; a cover disposed over the base and comprising a second surface facing the first surface and a second recess; a first film placed over the first surface to cover the first recess; a second film placed over the second surface to cover the second recess; and a plurality of insertion sheets interposed between the first film and the second film. The one or more deposition masks comprise a first mask interposed between first and second insertion sheets, the first mask having a width defining a width direction. Each of the first and second insertion sheets comprises a plurality of openings, each extending along the width direction when viewed in a viewing direction perpendicular to the first surface.
