Mask stick and mask assembly including the same
One or more embodiments provides a mask assembly including a frame defining an opening, a mask stick above the frame, extending in a first direction, defining through-holes, and including pattern areas that include one or more first non-hole portions in which no through-hole exists, and one or more second non-hole portions in which no through-hole exists, and a first support stick between the frame and the mask stick, extending in a second direction crossing the first direction, and overlapping the one or more second non-hole portions.
1 . A mask assembly comprising:
a frame defining an opening;
a mask stick above the frame, extending in a first direction, defining through-holes therein, and comprising:
pattern areas that comprise one or more first non-hole portions in which no through-hole exists at a first side of the mask stick; and
one or more second non-hole portions in which no through-hole exists at a second side of the mask stick; and
a first support stick between the frame and the mask stick, extending in a second direction crossing the first direction, and overlapping the one or more second non-hole portions,
wherein the second side is disposed opposite to the first side with respect to a longitudinal central axis of the mask stick.
2 . The mask assembly of claim 1 , wherein the pattern areas are divided by areas where the mask stick and the first support stick overlap.
3 . The mask assembly of claim 1 , wherein a number of the one or more first non-hole portions is equal to a number of the one or more second non-hole portions of the mask stick.
4 . The mask assembly of claim 1 , wherein the mask stick is configured to be fixed to the frame to be tensioned in the first direction.
5 . The mask assembly of claim 1 , wherein the one or more first non-hole portions and the one or more second non-hole portions have a same planar area.
6 . The mask assembly of claim 1 , wherein the one or more first non-hole portions or the one or more second non-hole portions comprises concave portions at a surface of the mask stick, and having a thickness that is less than a thickness of the mask stick.
7 . The mask assembly of claim 1 , wherein the one or more first non-hole portions or the one or more second non-hole portions comprises concave portions at regular intervals.
8 . The mask assembly of claim 1 , wherein the one or more first non-hole portions or the one or more second non-hole portions comprises concave portions having a same planar shape.
