Organic layer deposition apparatus, method of manufacturing organic light-emitting display apparatus using the same, and organic light-emitting display apparatus manufactured using the method

1. A method of manufacturing an organic light-emitting display apparatus by using an organic layer deposition apparatus for forming an organic layer on a substrate, the method comprising:

attaching a substrate to a transfer unit in a loading unit;

transporting, into a chamber, the transfer unit to which the substrate is attached, by using a first conveyer unit passing through the chamber;

depositing deposition materials discharged from a plurality of organic layer deposition assemblies to form organic layers on the substrate while the substrate is moved relative to the organic layer deposition assemblies, the organic layer deposition assemblies being in the chamber and spaced apart from the substrate;

separating from the transfer unit the substrate on which the depositing has been completed in an unloading unit; and

transporting the transfer unit from which the substrate is separated to the loading unit by using a second conveyer unit installed to pass through the chamber, wherein

each of the plurality of organic layer deposition assemblies comprises:

a plurality of deposition sources, each of the plurality of deposition sources being configured to discharge a corresponding one of a plurality of deposition materials; and

a deposition source nozzle unit at a side of each of the deposition sources, and comprising one or more deposition source nozzles,

the organic layer deposition assemblies comprise a plurality of common layer deposition assemblies for forming a common layer and a plurality of pattern layer deposition assemblies for forming a pattern layer,

each of the pattern layer deposition assemblies further comprises a correction slit sheet comprising a plurality of correction slits,

the correction slits of the pattern layer deposition assemblies are offset with respect to each other along a first direction in which the substrate is transported, and

the substrate is spaced apart from the organic layer deposition apparatus so as to be relatively movable with respect to the organic layer deposition apparatus, and

the deposition materials discharged from the deposition sources pass through respective said correction slit sheets and are deposited in a pattern on the substrate.

2. The method of claim 1 , wherein the chamber accommodates the organic layer deposition assemblies with which deposition is continuously performed on the substrate.

3. The method of claim 1 , wherein the transfer unit circulates between the first conveyer unit and the second conveyer unit.

4. The method of claim 1 , wherein the first conveyer unit and the second conveyer unit are arranged in parallel and one on top of the other.

5. The method of claim 1 , wherein a length of patterning slit sheets of the organic layer deposition assemblies in at least one of the first direction or a second direction perpendicular to the first direction is less than that of the substrate.

6. The method of claim 1 , wherein each of the correction slits extends in the first direction.

7. The method of claim 1 , wherein locations of the correction slits of the correction slit sheets in different pattern layer deposition assemblies are different from each other in the first direction.

8. The method of claim 1 , wherein a length of the correction slits of the correction slit sheets increases as the correction slits are farther away from respective centers of the correction slit sheets.

9. The method of claim 1 , further comprising

a correction plate located at a side of a corresponding one of the correction slit sheets and shielding at least a portion of the deposition material discharged from the deposition source.

10. The method of claim 9 , wherein

a width of the correction plate decreases from a center towards an edge of a corresponding one of the correction slit sheets.

11. The method of claim 10 , wherein the correction plate has a shape of a circular arc or cosine.

12. The method of claim 9 , wherein a width of the correction plate at a region corresponding to a center of a corresponding one of the correction slit sheets is greater than that at an edge of the correction plate.

13. The method of claim 9 , wherein the correction plate has a shape such that the deposition material is better shielded at a center of the correction slit sheet than at an edge of the correction slit sheet.
