  • Mask frame assembly for thin layer deposition and method of manufacturing organic light emitting display device by using the mask frame assembly
    Patent number: 8604489
    Abstract: A mask frame assembly for thin film deposition includes a frame including an opening portion, and a plurality of unit mask strips that are fixed to the frame after a tensile force is applied to both of end portions of the unit mask strips in a lengthwise direction of the unit mask strips. Each of the plurality of unit mask strips includes a plurality of unit masking pattern portions each including a plurality of opening patterns. Before the tensile force is applied to both of the end portions of the unit mask strips in the lengthwise direction and the unit mask strips are fixed to the frame, a width of each of the unit masking pattern portions in a widthwise direction perpendicular to the lengthwise direction increases as a function of a closeness of a portion of the unit masking pattern portion where the width is measured to a central portion of each of the unit masking pattern portions.
