Abstract

The present disclosure provides a display device that includes a first lower film, a second lower film extended toward one side of the first lower film, and a third lower film extended toward another side of the first lower film; a first upper film, a second upper film extended toward one side of the first upper film, and a third upper film extended toward another side of the first upper film; subpixels formed between the first lower film and the first upper film; and a sealing layer formed between the first to third lower films and the first to third upper films.

Claims (22)

1. A display device comprising:

a first lower film, a second lower film extended toward one side of the first lower film, and a third lower film extended toward another side of the first lower film;

a first upper film, a second upper film extended toward one side of the first upper film, and a third upper film extended toward another side of the first upper film;

subpixels formed between the first lower film and the first upper film;

a sealing layer formed between the first to third lower films and the first to third upper films, and

a touch screen layer disposed between the first to third upper films and the sealing layer,

wherein the touch screen layer does not exist in a bending area indicating a portion of a film which is able to be bent.

2. The display device of claim 1 , wherein the second lower film, the second upper film, the third lower film, and the third upper film have extension areas.

3. The display device of claim 2 , wherein the second lower film and the second upper film have a first bending area which is a bendable portion of the extension area of the second lower film and the second upper film, and

wherein the third lower film and the third upper film have a second bending area which is a bendable portion of the extension area of the third lower film and the third upper film.

4. The display device of claim 2 , further comprising a back plate attached onto a rear surface of the first to third lower films,

wherein the back plate does not exist in the bending area indicating the portion of the film which is able to be bent.

5. The display device of claim 1 , wherein a display area formed by the first lower film and the first upper film has a round, square, polygon, or eclipse shape.

6. The display device of claim 1 , wherein the touch screen layer exists in a display area between the first lower film and the first upper film, and exists either in an extension area of the second lower film and the second upper film or in an extension area of the third lower film and the third upper film.

7. A method of manufacturing a display device, the method comprising:

forming subpixels on a lower film;

performing a bonding and sealing procedure of disposing an upper film on the lower film and providing a sealing layer and a touch screen layer between the lower film and the upper film; and

performing a film cutting procedure so that the lower film has a first lower film, a second lower film extended toward one side of the first lower film, and a third lower film extended toward another side of the first lower film, and the upper film has a first upper film, a second upper film extended toward one side of the first upper film, and a third upper film extended toward another side of the first upper film,

wherein the touch screen layer does not exist in a bending area indicating a portion of a film which is able to be bent.

8. The method of claim 7 , further comprising:

forming a first bending area by bending a portion of the second lower film and a portion of the second upper film; and

forming a second bending area by bending a portion of the third lower film and a portion of the third upper film.
