Abstract

A mask frame assembly for deposition includes: a frame including an opening portion; a first support extending in a first direction across the opening portion and including opposing ends in the first direction which are each coupled to the frame; a mask stick through which a deposition material passes to a plurality of display regions of a substrate, the mask stick disposed on the first support and extending in a second direction crossing the first direction, the mask stick including: opposing ends in the second direction which are each coupled to the frame, and a deposition region common to each of the plurality of display regions of the substrate; and a magnet coupled to the first support and overlapping the deposition region of the mask stick.

Claims (31)

1. A mask frame assembly for deposition, comprising:

a frame comprising an opening portion;

a first support extending in a first direction across the opening portion, and comprising opposing ends in the first direction which are each coupled to the frame;

a mask stick through which a deposition material is passable to a plurality of display regions of a substrate, the mask stick disposed on the first support and extending in a second direction crossing the first direction, the mask stick comprising:

opposing ends in the second direction which are each coupled to the frame, and

a deposition region at which the deposition material is passable to the substrate, a same one of the deposition region disposed common to each of the plurality of display regions of the substrate; and

a magnet coupled to the first support and overlapping the deposition region of the mask stick, wherein

the deposition region includes a plurality of deposition openings, and

a portion of the plurality of deposition openings is masked by the magnet.

2. The mask frame assembly of claim 1 , wherein the magnet is between the same one of the deposition region of the mask stick and the first support.

3. The mask frame assembly of claim 1 , wherein

a surface of the first support facing the same one of the deposition region of the mask stick comprises a magnet groove or magnet slot, and

the magnet is disposed in the magnet groove or magnet slot.

4. The mask frame assembly of claim 3 , wherein the surface of the first support facing the same one of the deposition region of the mask stick and a surface of the magnet facing the mask stick are coplanar with each other.

5. The mask frame assembly of claim 1 , wherein

a width of the first support is defined in the second direction,

a surface of the first support facing the same one of the deposition region of the mask stick includes a magnet groove or magnet slot extended across a portion of the width of the first support, and a remaining portion of the width of the first support defines a blocking portion of the first support,

the magnet is disposed in the magnet groove or magnet slot extended across the portion of the width of the first support, and

an edge of the blocking portion is aligned with an edge of the first support which extends in the first direction, the blocking portion of the first support restricting movement in the second direction of the magnet disposed in the magnet groove or magnet slot.

6. The mask frame assembly of claim 1 , wherein a surface of the first support facing the same one of the deposition region of the mask stick, a surface of the magnet facing the same one of the deposition region of the mask stick, and a surface of the frame facing the mask stick are coplanar with each other.

7. The mask frame assembly of claim 1 , further comprising a second support below the mask stick,

the second support extending in the second direction, crossing the first support and comprising opposing ends in the second direction which are each coupled to the frame.

8. The mask frame assembly of claim 7 , wherein the second support is between the first support and the frame.

9. The mask frame assembly of claim 7 , wherein

the frame comprises first supporting grooves opposing each other in the first direction with respect to the opening portion and second supporting grooves opposing each other in the second direction with respect to the opening portion, and

the opposing ends of the first support are respectively inserted in the first supporting grooves,

the opposing ends of the second support are respectively inserted in the second supporting grooves, and

from a same surface of the frame which faces the mask stick, a depth of the first supporting grooves is less than that of the second supporting grooves.

10. The mask frame assembly of claim 7 , wherein a length of the first support in the first direction is greater than a length of the second support in the second direction.

11. The mask frame assembly of claim 1 , wherein the mask stick comprises a ferromagnetic material.

12. The mask frame assembly of claim 2 , wherein the first support together with the magnet between the same one of the deposition region of the mask stick and the first support divides the same one of the deposition region into a plurality of deposition areas spaced apart from each other along the second direction, the plurality of deposition areas corresponding to the plurality of display regions of the substrate.
