METHOD OF MANUFACTURING ORGANIC LIGHT-EMITTING DISPLAY APPARATUS

1 . A method of manufacturing an organic light-emitting display apparatus, the method comprising:

forming a deposition blocking film on regions of a substrate other than a display region of the substrate;

forming a common thin-film layer in the display region by deposition on the substrate on which the deposition blocking film is formed; and

removing the deposition blocking film from the substrate after the deposition is complete.

2 . The method of claim 1 , wherein the deposition blocking film comprises an adhesive film that is attachable and detachable to and from the regions of the substrate other than the display region.

3 . The method of claim 2 , wherein the forming of the deposition blocking film comprises:

preparing a material film comprising the adhesive film adhered to a base sheet;

moving the material film along an outer circumference of a pressing roller that rotates in tight contact with the substrate;

attaching the adhesive film to the substrate by passing the material film between the pressing roller and the substrate; and

removing the base sheet from the adhesive film by tightly moving a removing roller having an adhesive force on an outer circumference thereof on the material film that is attached to the substrate.

4 . The method of claim 2 , wherein the forming of the deposition blocking film comprises:

preparing a material film comprising the adhesive film adhered to a base sheet;

attaching edges of the material film to an outer-frame member, a central region of which is exposed;

attaching the adhesive film to the substrate by pressing the material film using a pressing roller after placing the outer-frame member on the substrate; and

detaching the base sheet from the adhesive film by tightly moving a removing roller having an adhesive force on an outer circumference thereof on the material film that is attached to the substrate.

5 . The method of claim 2 , wherein the removing of the deposition blocking film comprises detaching the adhesive film from the substrate by tightly moving a removing roller having an adhesive force on an outer circumference thereof on the adhesive film that is attached to the substrate.

6 . The method of claim 2 , further comprising aligning attaching points of the adhesive film and the substrate.

7 . The method of claim 6 , wherein the aligning the attaching points comprises:

forming aligning marks respectively on the adhesive film and the substrate; and

aligning the attaching points of the adhesive film and the substrate by using a camera to verify the alignment of the aligning marks.

8 . The method of claim 1 , wherein the deposition blocking film comprises a coating film.

9 . The method of claim 8 , wherein the forming of the deposition blocking film comprises:

coating a coating material on the substrate; and

forming the coating film by drying the coated coating material.

10 . The method of claim 8 , wherein the removing of the deposition blocking film comprises detaching the coating film from the substrate by tightly moving a removing roller having an adhesive force on an outer circumference thereof on the coating film formed on the substrate.

11 . The method of claim 1 , wherein the common thin-film layer comprises at least one of a hole injection-transport layer for supplying holes to a light-emitting layer included in each pixel in the display region, an electron injection-transport layer for supplying electrons to the light-emitting layer, a facing electrode that faces a pixel electrode with the light-emitting layer interposed therebetween, or a thin film sealing layer that seals the display region.
