Manufacturing method of multi-imposition vapor deposition mask preparation body and multi-imposition vapor deposition mask preparation body

摘要

PROBLEM TO BE SOLVED: To provide a method for manufacturing a multi-imposition vapor deposition mask capable of satisfying both high definition and light weight even when the size is increased. A step of preparing a frame, a plurality of metal masks provided with slits, and a resin film material corresponding to each of the metal masks, and a step of attaching the plurality of metal masks to the frame. Before and after the step of attaching the metal mask to the frame, the step of attaching the resin film material to the plurality of metal masks and the opening corresponding to the pattern of processing the resin film material to produce vapor deposition. A multi-imposition vapor deposition mask is manufactured by a step of manufacturing a resin mask by forming a portion. [Selection diagram] Fig. 6
