Apparatus and method for manufacturing display apparatus
An apparatus for manufacturing a display apparatus includes: a chamber; a mask assembly disposed in the chamber on a first side of a display substrate; a deposition source disposed to face the mask assembly and supplying a deposition material that passes through the mask assembly; and a magnetic force portion including a plurality of magnets extending in a first direction parallel to the mask assembly and disposed on a side opposite to the first side of the display substrate. The magnetic force portion reciprocates in a direction intersecting the first direction.
1. An apparatus for manufacturing a display apparatus, the apparatus comprising:
a chamber;
a mask assembly disposed in the chamber on a first side of a display substrate;
a deposition source disposed to face the mask assembly and supplying a deposition material that passes through the mask assembly; and
a magnetic force portion comprising a plurality of magnets extending in a first direction parallel to the mask assembly and disposed on a side opposite to the first side of the display substrate, wherein
the magnetic force portion repeatedly reciprocates in a direction intersecting the first direction while the deposition material is being deposited on the display substrate.
2. The apparatus of claim 1 , wherein the magnetic force portion repeats a first movement of moving from a stop position in the direction intersecting the first direction and returning to the stop position.
3. The apparatus of claim 2 , wherein, during the first movement, a distance that the magnetic force portion moves is less than a distance between adjacent ones of the plurality of magnets.
4. The apparatus of claim 2 , wherein, during the first movement, a distance that the magnetic force portion moves is a multiple of a distance between adjacent ones of the plurality of magnets.
5. The apparatus of claim 1 , wherein the direction intersecting the first direction is perpendicular to the first direction.
6. The apparatus of claim 1 , wherein the direction intersecting the first direction forms an acute angle with the first direction.

a first movement of moving from a stop position in the direction intersecting the first direction and returning to the stop position; and
a second movement of moving from the stop position in a direction opposite to the direction intersecting the first direction and returning to the stop position.
8. The apparatus of claim 1 , wherein
the magnetic force portion further comprises a support plate accommodating the plurality of magnets and capable of moving, and
the apparatus further comprising a driving portion that reciprocates the support plate in the direction intersecting the first direction.
9. The apparatus of claim 1 , wherein
the plurality of magnets are spaced apart from each other in a second direction intersecting the first direction,
the plurality of magnets comprises:
first magnets, each including a side facing the mask assembly having a polarity of N; and
second magnets, each including a side facing the mask assembly having a polarity of S, and
the first magnets and the second magnets are alternately arranged.
10. The apparatus of claim 9 , wherein a magnetic force of the magnetic force portion in the second direction comprises a sine curve.
11. The apparatus of claim 9 , wherein the magnetic force portion reciprocates in the second direction.
12. The apparatus of claim 9 , wherein
the mask assembly comprises a plurality of mask sheets extending in the second direction, and
the magnetic force portion reciprocates in the second direction.
