摘要： A manufacturing method of a mask assembly includes tensioning a mask sheet, connecting the tensioned mask sheet with a mask frame, and defining opening processing areas in the tensioned mask sheet to form openings respectively corresponding to the opening processing areas. The defining of the opening processing areas includes defining initial opening processing areas in the tensioned mask sheet in a first direction and in a second direction crossing the first direction to determine a processing sequence of the initial opening processing areas, calculating cumulative deformation amounts accumulated in each of the initial opening processing areas based on the processing sequence, and correcting a size and a position of each of the initial opening processing areas based on the cumulative deformation amounts.

摘要： A mask includes a mask sheet provided with a plurality of open areas defined therein in a plan view and a mask frame which supports the mask sheet. The mask sheet includes a first portion including a first surface, where the first surface is configured to be in contact with a target substrate, and a second portion disposed on the first portion, extending from a top of the first portion in a first direction and including a second surface defining the open area. The second surface is an inclined surface inclined downward with respect to the first direction, and the first direction is parallel to a plane in which the first surface is included.

摘要： A display device includes a window including a front area and a corner area, and a display panel coupled to the window. The display panel includes a first area and a second area corresponding to the front area and the corner area, respectively. The second area includes a plurality of unit areas, a plurality of stretchable areas disposed between the plurality of unit areas, where a plurality of opening areas are defined through the display panel to be adjacent to the plurality of unit areas . A light emitting area of the second area has an area greater than an area of a corresponding light emitting area of the first area.
