MASK ASSEMBLY FOR THIN FILM VAPOR DEPOSITION AND MANUFACTURING METHOD THEREOF

摘要

A mask assembly for thin film deposition comprises: a frame body for forming an opening; a plurality of unit masks in which both ends are fixed to the frame body while tension is applied in a first direction; and an end tension unit mounted to the frame body. The end tension unit is used to elongate the ends of the unit mask in a second direction by moving along the second direction which intersects with the first direction between two adjacent unit masks among the plurality of unit masks.
