Abstract: A mask assembly includes: a mask frame; a mask supported by the mask frame, the mask including a plurality of pattern holes; and a magnetic part disposed on one surface of the mask. The magnetic part provides a magnetic force between the mask and a target substrate and improves an adhesion between the mask and the target substrate to prevent deposition defects.
