Abstract: A mask assembly and an apparatus for manufacturing a display apparatus are provided. The mask assembly includes a mask frame including an opening area, at least one mask sheet covering the opening area of the mask frame, and a support stick disposed between the mask frame and the at least one mask sheet, extending in a first direction to traverse the opening area, and having both ends fixed to the mask frame. The at least one mask sheet includes submasks disposed side by side in a direction intersecting the first direction in which the support stick extends, and a connection stick disposed between the submasks and connecting two adjacent submasks among the submasks. The connection stick overlaps the support stick in a plan view.

Abstract: A mask frame assembly includes: a mask frame; at least one mask sheet arranged on the mask frame; a plurality of first support sticks extending in a first direction; and a plurality of second support sticks extending in a second direction, wherein a mask frame transformation index is within a range from about −1000 to about +1000 based on mask frame transformation index=Σ (tensile force of first support sticks/tensile rate of first support sticks)−Σ (tensile force of second support sticks/tensile rate of second support sticks), where tensile force of respective first or second support stick is given by thickness (T)×width (W)×elastic coefficient (E)×tensile rate (δ/L0), δ is a transformed amount (Lf−L0) corresponding to tension, L0 is an initial length of respective first or second support stick, and Lf is a final length of respective first or second support stick.
