and a support bar that crosses the opening, having both ends thereof installed on the frame and configured to support the rib portion, wherein the mask includes first alignment holes, which are formed in the rib portion and through which the deposition material passes, and the support bar includes second alignment holes configured to overlap with the first alignment holes based on an injection direction of the deposition material. ## Claims ### Claim 1 A mask frame assembly, comprising: a frame having an opening formed therein; a mask comprising a pattern portion configured for a deposition material to pass through the mask frame assembly, and a rib portion surrounding the pattern portion and configured to block the deposition material, both ends of the mask being installed on the frame; and a support bar configured to support the rib portion, the support bar having both ends thereof installed on the frame to crosses the opening, wherein: the mask comprises first alignment holes, which are formed in the rib portion and through which the deposition material passes; and the support bar comprises second alignment holes configured to overlap with the first alignment holes based on an injection direction of the deposition material. ### Claim 2 (depends on 1) The mask frame assembly of claim 1, wherein the substrate comprises alignment keys adjacent to the first alignment holes and the second alignment holes based on the injection direction of the deposition material, and a deposition position of the deposition material deposited on a substrate while sequentially passing through the first alignment holes and the second alignment holes and a position of the alignment keys are configured for alignment of the substrate and the mask relative to each other. ### Claim 3 (depends on 2) The mask frame assembly of claim 2, wherein the alignment keys comprise a plurality of reference lines, and the first alignment holes are formed at different positions of the mask so that the deposition material is deposited adjacent to one of the plurality of reference lines. ### Claim 4 (depends on 2) The mask frame assembly of claim 2, wherein the alignment keys comprise a plurality of reference lines, and the second alignment holes are formed at different positions of the support bar so that the deposition material is deposited adjacent to one of the plurality of reference lines. ### Claim 5 (depends on 1) The mask frame assembly of claim 1, wherein the frame comprises accommodation grooves for accommodating both ends of the support bar, and both ends of the support bar are accommodated in the accommodation grooves and are combined with the frame. ### Claim 6 (depends on 1) The mask frame assembly of claim 1, wherein at least a part of the deposition material that passes through the first alignment holes passes through the second alignment holes. ### Claim 7 (depends on 1) The mask frame assembly of claim 1, wherein the mask crosses the support bar at right angles. ### Claim 8 (depends on 1) The mask frame assembly of claim 1, wherein the mask comprises at least one strip mask.
