## Abstract

An organic light emitting display device and a method of manufacturing the same are proposed. The organic light emitting display device includes: a first film formed of an organic material, and having first and second surfaces facing each other and a third surface perpendicular to the first and second surfaces; a second film formed on the first film to cover the second and third surfaces of the first film; an organic light emitting unit disposed on the second film; a third film disposed on the second film to cover the organic light emitting unit; and a fourth film disposed on the third film, formed of an organic material, and having fourth and fifth surfaces facing each other, wherein the fifth surface faces the third film.

## Claims

### Claim 1

An organic light emitting display device comprising:
a first film formed of an organic material, and having first and second surfaces facing each other and a third surface perpendicular to the first and second surfaces;
a second film formed on the first film to cover the second and third surfaces of the first film, wherein the second film comprises inorganic and organic materials, the inorganic and organic materials being electrically insulating materials;
an organic light emitting unit disposed on the second film, the organic light emitting unit comprising:
a thin film transistor formed on the second film;
a pixel electrode electrically connected to the thin film transistor;
a pixel defining film covering edges of the pixel electrode;
an organic light emitting layer formed on the pixel electrode; and
a counter electrode formed on the organic light emitting layer,
a third film disposed on the second film and covering the organic light emitting unit; and
a fourth film disposed on the third film, formed of an organic material, and having fourth and fifth surfaces facing each other, the fifth surface facing the third film.

### Claim 2 (depends on 1)

The organic light emitting display device of claim 1, further comprising a side barrier disposed on the second film and surrounding the organic light emitting unit.

### Claim 3 (depends on 2)

The organic light emitting display device of claim 2, wherein the side barrier contacts at least a side surface of the third film.

### Claim 4 (depends on 2)

The organic light emitting display device of claim 2, wherein the side barrier comprises a hybrid polymer.

### Claim 5 (depends on 2)

The organic light emitting display device of claim 2, wherein the side barrier forms a closed loop.

### Claim 6 (depends on 1)

The organic light emitting display device of claim 1, further comprising a fifth film disposed between the fifth surface of the fourth film and the third film, the fifth film including an inorganic layer.

### Claim 7 (depends on 1)

The organic light emitting display device of claim 1, wherein the third film comprises an adhesive.

### Claim 8 (depends on 1)

The organic light emitting display device of claim 1, further comprising a barrier being disposed between the third film and the organic light emitting unit to cover the organic light emitting unit.
