Organic light-emitting display device and method of manufacturing the same

1. An organic light-emitting display device, comprising:

a first film comprising an inorganic material;

a second film that comprises an organic material and is formed on the first film, and comprises a first surface and a second surface facing each other and lateral surfaces at boundaries of the first surface and the second surface, with the first surface contacting the first film;

a third film that comprises an inorganic material and covers the second surface and the lateral surfaces of the second film, with a first sealing region contacting the first film being to located between a boundary of the second film and a boundary of the third film;

an organic light-emitting unit disposed on the third film to overlap with the second film; and

a fourth film that covers the organic light-emitting unit, with a second sealing region contacting the third film being located between a boundary of the organic light-emitting unit and a boundary of the fourth film.

2. The organic light-emitting display device of claim 1 , wherein the first film and the third film comprise the same material.

3. The organic light-emitting display device of claim 1 , wherein at least one of the first film and the third film comprises a plurality of layers, and at least one of the plurality of layers comprises inorganic materials.

4. The organic light-emitting display device of claim 1 , wherein the fourth film comprises a layer comprising an inorganic material and a layer comprising an organic material.

5. The organic light-emitting display device of claim 1 , wherein the first sealing region is formed to surround the second film.

6. The organic light-emitting display device of claim 1 , wherein the second sealing region is formed to surround the organic light-emitting unit.

7. A method of manufacturing an organic light-emitting display device, the method comprising:

forming, on a glass substrate, an auxiliary film comprising an inorganic material;

forming, on the auxiliary film, a first film comprising an inorganic material;

forming, on the first film, a second film that comprises an organic material and includes a first surface and a second surface facing each other and lateral surfaces at boundaries of the first surface and the second surface, with the first surface contacting the first film;

forming a third film that comprises an inorganic material and covers the second surface and the lateral surfaces of the second film, with a first sealing region contacting the first film to being located between a boundary of the second film and a boundary of the third film;

forming an organic light-emitting unit that is disposed on the third film to overlap with the second film;

forming a fourth film that covers the organic light-emitting unit, with a second sealing region contacting the third film being located between a boundary of the organic light-emitting unit and a boundary of the fourth film; and

separating the auxiliary film and the first film.

8. The method of claim 7 , wherein the first film and the third film comprise the same material.

9. The method of claim 7 , wherein at least one of the first film and the third film comprises a plurality of layers, and at least one of the plurality of layers comprises inorganic materials.

10. The method of claim 7 , wherein the fourth film comprises a layer comprising an inorganic material and a layer comprising an organic material.

11. The method of claim 7 , wherein the first sealing region is formed to surround the second film.

12. The method of claim 7 , wherein the second sealing region is formed to surround the organic light-emitting unit.

13. The method of claim 7 , wherein the separation of the auxiliary film and the first film comprises irradiating a laser beam from a lower portion of the glass substrate to the auxiliary film.

14. The method of claim 7 , wherein the auxiliary film comprises a micro-crystal silicon, titanium, or molybdenum.
