1. A mask frame assembly, comprising:
- a frame; and
a mask tensioned on the frame in a first direction, the mask including;
a deposition pattern portion having a plurality of pattern holes therethrough, a deposition material being deposited on a substrate through the pattern holes, anda dummy portion extending from the deposition pattern portion in the first direction, the dummy portion having an increased thickness in a second direction as a distance from the deposition pattern portion in the first direction increases.
