Mask frame assembly and method of manufacturing the same

Abstract

A mask frame assembly for manufacturing a display device, and a method of manufacturing the mask frame assembly are disclosed. In one aspect, the mask frame assembly includes a frame having at least one opening portion defined therein. The mask frame assembly further includes a polymer film having a plurality of slits defined therein and combined to the frame.

What is claimed is: 
     
         1 . A mask frame assembly for manufacturing a display device, the mask frame assembly comprising:
 a frame having at least one opening portion defined therein; and   a polymer film having a plurality of slits defined therein and combined to the frame.   
     
     
         2 . The mask frame assembly of  claim 1 , wherein the frame is formed at least partially of a metal. 
     
     
         3 . The mask frame assembly of  claim 1 , further comprising an adhesive layer being interposed between the frame and the polymer film and adhering the frame and the polymer film. 
     
     
         4 . The mask frame assembly of  claim 2 , further comprising an adhesive layer being interposed between the frame and the polymer film and adhering the frame and the polymer film. 
     
     
         5 . The mask frame assembly of  claim 1 , wherein the polymer film comprises one or more of: polyimide, polyphenylene sulfide, polyaryletherketone, and liquid crystal polymer. 
     
     
         6 . The mask frame assembly of  claim 5 , wherein the polymer film comprises a pattern portion and the slits are formed on the pattern portion. 
     
     
         7 . The mask frame assembly of  claim 6 , wherein the pattern portion comprises a plurality of pattern portions, wherein the at least one opening portion comprises a plurality of opening portions, and wherein the number of the pattern portions is the same as the number of the opening portions. 
     
     
         8 . The mask frame assembly of  claim 7 , wherein the lengths and widths of the opening portions are substantially the same. 
     
     
         9 . The mask frame assembly of  claim 6 , wherein the opening portion is formed in a location corresponding to the pattern portion. 
     
     
         10 . The mask frame assembly of  claim 9 , wherein the opening portion is formed substantially directly below the pattern portion. 
     
     
         11 . The mask frame assembly of  claim 1 , wherein the thickness of the polymer film is in the range from about 10 μm to about 50 μm. 
     
     
         12 . The mask frame assembly of  claim 1 , wherein the polymer film has a coefficient of thermal expansion (CTE) of about 3 ppm/° C. or less.
