Abstract

Provided are a display apparatus and a method of manufacturing the display apparatus. The display apparatus includes: a substrate including a bending area located between a first area and a second area and bent in the bending area; a display unit arranged over an upper surface of the substrate and located in the first area; a protection film located over a lower surface of the substrate and including a protection film base and a viscous layer; and a bending protection layer including a first bending protection layer and a second bending protection layer and corresponding to the bending area, wherein the protection film is located over the lower surface of the substrate and has an opening corresponding to the bending area or at least a part of the first area, and wherein the first bending protection layer is arranged over at least a part of a boundary of the opening or over an outside of the boundary of the opening, and at least a part of the second bending protection layer is arranged over an inside of the boundary of the opening.

Claims (26)

1. A method of manufacturing a display apparatus, the method comprising:

forming a display unit in a first area of a substrate comprising a bending area located between the first area and a second area;

attaching a protection film onto a lower surface of the substrate, wherein the protection film comprises a protection film base and a viscous layer, the protection film base not directly contacting the substrate;

forming a first bending protection layer over the substrate corresponding to at least a part of a boundary of an opening or over the substrate of an outside of the boundary of the opening and curing the first bending protection layer; and

forming a second bending protection layer over the substrate so that at least a part of the second bending protection layer corresponds to an inside of the boundary of the opening.

2. The method of claim 1 , further comprising:

attaching a carrier film onto the protection film.

3. The method of claim 1 , further comprising:

curing the second bending protection layer.

4. The method of claim 1 , wherein at least a part of the second bending protection layer overlaps the first bending protection layer.

5. The method of claim 1 , wherein a maximum height of the first bending protection layer is greater than a maximum height of the second bending protection layer.

6. The method of claim 1 , wherein a point corresponding to a maximum height of the first bending protection layer is outside the boundary of the opening.

7. The method of claim 1 , wherein the first bending protection layer is arranged over the substrate and overlaps the boundary of the opening.

8. The method of claim 1 , wherein the first bending protection layer is formed in a closed loop.

9. The method of claim 1 , wherein an area of the bending protection layer is greater than an area of the opening.

10. The method of claim 1 , wherein an area of the opening is greater than an area of the bending area.

11. The method of claim 1 , further comprising:

bending the substrate with respect to a bending axis in the bending area.

12. The method of claim 11 , further comprising:

at least partially filling the opening with a filler after bending the substrate.

13. The method of claim 11 , further comprising:

arranging a cushion layer between the first area and the second area after the bending of the substrate.

14. The method of claim 1 , further comprising:

coating the opening with a liquefied or paste filler.

15. The method of claim 14 , further comprising:

curing the liquefied or paste filler.
