Abstract
Provided is a method of manufacturing a deposition mask frame assembly, the method including placing and welding a support stick mask and a gap stick mask on a frame, and joining edges of a deposition stick mask with the frame by welding while the deposition stick mask is tensioned in a longitudinal direction of the X-axis direction and at the same time, adhesively tensioned in the Y-axis direction, thereby preventing wrinkles due to the tensioning of the deposition stick mask to manufacture a fine and high-quality deposition mask frame assembly.
