A mask for large scale evaporation and a manufacturing method thereof are provided to improve accuracy of alignment by reducing intensity of tension applied to a metal mask, thereby increasing yield of an evaporation process. A mask for large scale evaporation includes a frame(250) and a plurality of metal masks(260). The frame has equally divided four opening units(250a) to expose an evaporation region of a substrate and a blocking unit(250b) to divide the opening units. The plurality of metal masks are placed to correspond to the four opening units of the frame, and ends thereof are fixed to the blocking unit and an edge region(250c) of the frame through welding while tension is applied. |
