Abstract

A method of manufacturing a display panel, including providing a plurality of display substrates spaced apart from each other by a predetermined area disposed therebetween when viewed in a plan view, each of the display substrates including a display area, on which an image is displayed, and each of the display substrates being flexible; attaching a first film onto the display substrates to overlap with the display substrates; attaching a second film onto the first film; and substantially and simultaneously cutting the first and second films along a cutting line defined in an area overlapping with the predetermined area.

Claims (24)

1. A method of manufacturing a display panel, comprising:

providing a plurality of display substrates spaced apart from each other by a predetermined area disposed therebetween, each of the plurality of display substrates including a display area, on which an image is displayed, and each of the plurality of display substrates being flexible;

attaching a first film on the plurality of display substrates to overlap the plurality of display substrates;

attaching a second film on the first film; and

cutting the first and second films along a cutting line to form matched edges of the first and second films and to form a first flexible substrate and a second flexible substrate,

wherein each of the first and second flexible substrates overlaps at least one of the plurality of display substrates,

wherein providing the plurality of display substrates further includes cutting a mother substrate, the mother substrate including a base layer and a plurality of cells on the base layer and spaced apart from each other, each of the cells defining the display area, and

wherein the mother substrate is cut in a unit of the cells to form the plurality of display substrates.

2. The method as claimed in claim 1 , wherein an edge portion of the first flexible substrate and an edge portion of the second flexible substrate are aligned with each other.

3. The method as claimed in claim 2 , wherein cutting the first and second films includes using a laser beam or pressure.

4. The method as claimed in claim 1 , wherein the first film is an optical clear adhesive film.

5. The method as claimed in claim 4 , wherein attaching the second film includes:

disposing the second film on the first film; and

applying a heat to the second film to allow the first film to be adhered to the plurality of display substrates and the second film.

6. The method as claimed in claim 5 , wherein the second film is a touch panel including a plurality of touch areas disposed to respectively correspond to the plurality of display substrates.

7. The method as claimed in claim 1 , further comprising attaching a third flexible substrate to the second film after attaching the second film and before cutting the first and second films, wherein the third flexible substrate is cut with the first and second films.

8. The method as claimed in claim 1 , wherein the mother substrate further includes a cover layer on the base layer to cover the cells, and cutting the mother substrate includes cutting the base layer and the cover layer to form the plurality of display substrates respectively covered by cover substrates, the cover substrates formed by cutting the cover layer.

9. The method as claimed in claim 8 , wherein:

providing the plurality of display substrates further includes respectively removing the cover substrates from the plurality of display substrates, and

the first film is directly attached to the cells.

10. The method as claimed in claim 8 , further comprising:

attaching a third film overlapping the at least one of the plurality of display substrates after providing the plurality of display substrates; and

cutting the third film to form third flexible substrates respectively attached to the plurality of display substrates before attaching the first film, and

wherein the third film is cut along an edge portion of each of the plurality of display substrates.
