Abstract: A mask frame assembly includes a frame, a mask combined to the frame and including a pattern area for deposition on a substrate, and a long-side stick combined to the frame and dividing the pattern area of the mask into unit cell patterns. The long-side stick may include a clad structure in which a relatively ferromagnetic layer and a relatively weak magnetic layer are stacked.
