The first area includes a first opening pattern that is a half-etched pattern, the second area includes a second opening pattern that is a penetrating pattern, and in a plan view, the first opening pattern and the second opening pattern are different from each other.

Abstract: A mask assembly and a deposition device including the same are disclosed. A mask assembly includes: a mask frame, a first mask bar connected to the mask frame and extending in a first direction, and a second mask bar connected to the mask frame and extending in a second direction. The first mask bar overlaps the second mask bar in an overlapping region, the second mask bar includes a non-overlapping region not overlapping the first mask bar, the second mask bar includes a first portion having a first thickness and a second portion having a second thickness that is less than the first thickness in the non-overlapping region, and the first portion is located along an edge of the second mask bar.

Abstract: A supporting frame according to an embodiment includes a body part including a first frame part, a second frame part, a third frame part, and a fourth frame part disposed on a first side, a second side, a third side, and a fourth side of an opening, respectively, and a supporting bar coupled to the first frame part. The supporting bar has a shape convex toward an outside of the supporting frame.

Abstract: A mask assembly includes a mask frame including a plurality of ribs including a first rib extending in a first direction, the plurality of ribs defining an opening area, and a mask sheet disposed on a first surface of the first rib and covering the opening area, where the mask frame further includes a plurality of receiving portions disposed on a second surface of the first rib, and spaced apart from each other in a longitudinal direction of the first rib, the second surface being opposite to the first surface.

Abstract: A mask assembly includes a mask frame including a frame opening, a first stick disposed on the mask frame, overlapping the frame opening, and extending in a first direction to have a first length, a second stick disposed on the first stick, overlapping the frame opening, and extending in a second direction intersecting the first direction to have a second length longer than the first length, and a mask disposed on the second stick and including a mask opening overlapping the frame opening. The second stick includes a first center portion crossing the frame opening and a first end portion extending from the first center portion in the second direction.

Abstract: A mask assembly includes a mask frame including an opening area, mask sheets covering the opening area of the mask frame and arranged side by side in a first direction, and a support stick arranged between the mask frame and the mask sheets, extending in the first direction, and having ends fixed on the mask frame, wherein widths of ends of the support stick are greater than a width of a portion of the support stick that overlaps the opening area.

Abstract: A deposition apparatus includes: a chamber; a stage defining a stage-opening therein and disposed inside the chamber; a frame disposed on the stage and defining a frame-opening therein corresponding to the stage-opening; a mask coupled to the frame and defining a plurality of deposition openings therein corresponding to the frame-opening; a deposition source configured to spray a deposition material to the frame-opening; alignment units coupled to the stage and contacting the frame to move a position of the frame on the stage; and correction units each of which includes a magnetic force part disposed on the stage and adjacent to the frame, and a driving part configured to provide a magnetic force to the magnetic force part, wherein the correction units are configured to change a shape of the frame, and are coupled to the stage.

Abstract: A mask frame assembly includes a mask frame including: a first surface including a first long side part extending in a first direction, a first short side part extending in a second direction intersecting the first direction, and a first recessed part extending in the first direction or the second direction, a second surface opposite to the first surface and including a second long side part extending in the first direction, a second short side part extending in the second direction, and a second recessed part disposed in the first direction or the second direction, a third surface connected to the first surface and the second surface and defining a frame opening part; a first support member disposed in the first recessed part; and a second support member disposed in the second recessed part.

Abstract: A mask assembly includes a mask frame having an opening area, and a mask sheet disposed on the mask frame to overlap the opening area, the mask sheet including a first area, and a second area surrounding the first area. The first area includes a first opening pattern that is a half-etched pattern, the second area includes a second opening pattern that is a penetrating pattern, and in a plan view, the first opening pattern and the second opening pattern are different from each other.

Abstract: A mask frame assembly includes: a mask including a plurality of opening portions; and a frame coupled to an edge of the mask, wherein the mask includes: first shielding portions extending in a first direction and parallel to each other; second shielding portions parallel to each other and extending in a second direction crossing the first direction, such that the plurality of opening portions are defined together with the first shielding portions; and a first protrusion on the first shielding portion, wherein, in the second direction, a distance from an opening portion on one side of the first shielding portion is different from a distance from an opening portion on another side of the first shielding portion.
