A mask frame assembly includes a frame, an open mask, and stick masks. The open mask is supported by the frame. The stick masks are disposed on the open mask and include ends coupled to the frame. The open mask includes: a first opening disposed in association with opposing ends of the open mask; and a second opening disposed between the first openings, the second opening being larger than the first opening. First deposition patterns of a first stick mask of the stick masks and second deposition patterns of a second stick mask of the stick masks overlap the second opening.
