Organic Layer Deposition Apparatus, Frame Sheet Assembly For The Organic Layer Deposition Apparatus, And Method Of Manufacturing Organic Light Emitting Display Device Using The Frame Sheet Assembly

1 . An organic layer deposition apparatus for forming an organic layer on a substrate, the apparatus comprising:

a deposition source configured to discharge a deposition material;

a deposition source nozzle unit disposed at a side of the deposition source and comprising a plurality of deposition source nozzles arranged in a first direction;

a patterning slit sheet disposed to face the deposition source nozzle unit, having a plurality of patterning slits arranged in a second direction perpendicular to the first direction, and being smaller than the substrate in at least one of the first direction or the second direction; and

a correction sheet disposed between the deposition source nozzle unit and the patterning slit sheet to block at least some of the deposition material discharged from the deposition source,

wherein the organic layer deposition apparatus and the substrate are separated from each other, and

the substrate or the organic layer deposition apparatus is configured to be moved relative to the other in the first direction to perform a deposition.

2 . The apparatus of claim 1 , wherein the deposition source and the deposition source nozzle unit, and the patterning slit sheet are integrally connected as one body via a connection member for guiding movement of the deposition material.

3 . The apparatus of claim 2 , wherein the connection member seals a space between the deposition source nozzle unit disposed at the side of the deposition source, and the patterning slit sheet.

4 . The apparatus of claim 1 , wherein the plurality of deposition source nozzles are tilted at an angle.

5 . The apparatus of claim 4 , wherein the plurality of deposition source nozzles include deposition source nozzles arranged in two rows formed in the first direction, and the deposition source nozzles in the two rows are tilted to face each other.

6 . The apparatus of claim 1 , wherein the correction sheet is formed to block more deposition material at a center portion of the patterning slit sheet, than the deposition material blocked at end portions of the patterning slit sheet.

7 . The apparatus of claim 1 , wherein the correction sheet has an opening portion, and when going farther from the center of the patterning slit sheet, portions of the patterning slits exposed by the opening portion lengthen.

8 . The apparatus of claim 7 , wherein the correction sheet comprises a covering portion extending to be convex toward a center of the opening portion.

9 . The apparatus of claim 8 , wherein the covering portion comprises a first member and a second member both extending to be convex toward the center of the opening portion, and the first member and the second member are symmetrical to each other about a virtual central point of the opening portion.

10 . The apparatus of claim 1 , further comprising a frame supporting the correction sheet and the patterning slit sheet.

11 . The apparatus of claim 10 , wherein the frame further comprises a joining portion extending from one side of the frame and being joined to the correction sheet.

12 . The apparatus of claim 11 , wherein the joining portion is joined to the correction sheet by welding.

13 . The apparatus of claim 10 , wherein the correction sheet is disposed on and joined to the frame, and the patterning slit sheet is disposed on and joined to the correction sheet.

14 . The apparatus of claim 11 , wherein:

the frame further comprises a stepped portion extending from the joining portion; and

the correction sheet further comprises a coupling portion corresponding to the stepped portion and configured to be coupled to the stepped portion.

15 . The apparatus of claim 14 , wherein the coupling portion is formed to penetrate the correction sheet and be coupled to the stepped portion.
