Abstract

Provided are a mask assembly and a method of fabricating the same. The mask assembly includes a mask frame in which a frame opening is formed therein and insulation grooves are formed at both sides of a first direction with the frame opening therebetween. The mask has both ends disposed at the both sides and includes a plurality of pattern open parts configured by a plurality of pattern openings between the both ends. A movement member is provided in the insulation groove, to which the both ends of the mask are fixed, and which includes a movement block moving in the first direction and a second direction intersecting the first direction.

First claim

What is claimed is:

1. A mask assembly, comprising:
a mask frame comprising a frame opening and grooves disposed at opposite sides of the frame opening in a first direction;
a mask comprising two ends and a plurality of pattern open parts comprising a plurality of pattern openings disposed between the both ends; and
a movement member, disposed in each of the grooves, to which the two ends of the mask are fixed, the movement member comprising a movement block configured to move in both the first direction and a second direction intersecting the first direction,
wherein:
each of the grooves is formed along the second direction and is formed to be recessed from a top surface of the mask frame to a bottom surface of the mask frame, the top surface of the mask frame facing the mask; and
the mask directly contacts the movement block.

2. The mask assembly of claim 1 , wherein the mask comprises a plurality of divided masks arranged along the second direction or one mother mask.

3. The mask assembly of claim 1 , wherein the movement member further comprises a first screw coupled to a side surface of the mask frame and a side surface of the movement block and a second screw coupled to a bottom surface of the mask frame and a bottom surface of the movement block.

4. The mask assembly of claim 3 , wherein the side surface of the mask frame comprises a first through hole through which the first screw passes, the first screw comprises a first head part and a first body part coupled to the first head part to pass through the first through hole, wherein a width of the first through hole in the second direction is equal to or larger than a width of the first body part.

5. The mask assembly of claim 3 , wherein the bottom surface of the mask frame comprises a second through hole through which the second screw passes, the second screw comprises a second head part and a second body part coupled to the second head part to pass through the second through hole, wherein a width of the second through hole in the second direction is larger than a width of the second body part.

6. The mask assembly of claim 1 , wherein the movement block comprises a plurality of divided blocks arranged along the second direction, wherein a total area of the plurality of divided blocks is smaller than an area of the groove.

7. The mask assembly of claim 6 , wherein the mask comprises a plurality of divided masks arranged along the second direction or one mother mask, wherein a ratio of the plurality of divided masks and the corresponding plurality of divided blocks or a ratio of the one mother mask and the corresponding plurality of divided blocks is 1:n (n is a natural number).

8. The mask assembly of claim 6 , wherein the movement member further comprises a plurality of first screws coupled to a side surface of the mask frame and side surfaces of the plurality of divided blocks and a plurality of second screws coupled to a bottom surface of the mask frame and the plurality of divided blocks.

9. The mask assembly of claim 8 , wherein the side surface of the mask frame comprises a first through hole through which the first screw passes, the first screw comprises a first head part and a first body part coupled to the first head part to pass through the first through hole, wherein a width of the first through hole in the second direction is equal to or larger than a width of the first body part.

10. The mask assembly of claim 8 , wherein the bottom surface of the mask frame comprises a second through hole through which the second screw passes, the second screw comprises a second head part and a second body part coupled to the second head part to pass through the second through hole, wherein a width of the second through hole in the second direction is larger than a width of the second body part.

11. The mask assembly of claim 1 , further comprising:
a welding part comprising welds fixing the two ends of the mask to the movement block to be fixed.
