Abstract

The present disclosure relates to a protection member, a display apparatus and a method of manufacturing the display apparatus. The protection member includes a protective film including a first layer having a central area, a first side area extended to a first edge of the central area, a second side area intersecting the first edge of the central area, and a corner area extended between the first side area and the second side area, and a second layer arranged on the first layer and exposing at least a portion of the corner area of the first layer; and a shielding member shielding the at least the portion of the corner area exposed.

a second layer arranged on the first layer and including a groove exposing at least

a portion of the corner area of the first layer in a plan view; and

a shielding member shielding the at least the portion of the corner area that is exposed.

2. The protection member of claim 1 , wherein

the second layer overlaps the central area, the first side area, and the second side area of the first layer in the plan view, and

the second layer exposes the corner area of the first layer.

3. The protection member of claim 1 , wherein

the corner area comprises a first area and a second area,

the second layer overlaps the central area, the first side area, the second side area of the first layer, and the first area in the plan view, and

the second layer exposes the second area of the first layer.

4. The protection member of claim 3 , wherein the shielding member shields the second area and at least one of the central area, the first side area, the second side area, and the first area.

5. The protection member of claim 3 , wherein

the first area comprises a first line area and a second line area spaced apart from each other,

the first line area is positioned between the first side area and the second area, and

the second line area is positioned between the second side area and the second area.

6. The protection member of claim 5 , wherein the shielding member shields the second area and at least one of the central area, the first side area, and the second side area, the first line area, and the second line area.

7. The protection member of claim 3 , wherein

the first area comprises line areas that extend in a first direction and are spaced apart from each other in a second direction,

the second area comprises space areas that extend in the first direction and are arranged in the second direction, and

the line areas and the space areas are arranged to alternate with each other in the second direction.

8. The protection member of claim 7 , wherein the shielding member comprises:

a first shielding member shielding one of the space areas; and

a second shielding member shielding another one of the space areas.

9. The protection member of claim 1 , wherein the shielding member comprises:

a body portion; and

a contact layer contacting the second layer.

10. The protection member of claim 9 , wherein the contact layer comprises metal particles.

11. The protection member of claim 9 , wherein a surface of the body portion is flat.

12. The protection member of claim 9 , wherein the contact layer comprises:

a blocking layer arranged on the body portion; and

a conductive layer arranged on the blocking layer.

13. The protection member of claim 1 , wherein at least a portion of the shielding member is curved.

14. A display apparatus comprising:

a protective film comprising:

a first layer having:

a central area;

a side area extended to an edge of the central area; and

a corner area that extends from a corner of the central area and is bent at a first curvature radius; and

a second layer exposing at least a portion of the corner area of the first layer;

a shielding member shielding at least the portion of the corner area, the portion of the corner area being exposed; and

a display panel arranged on a second surface facing the first surface, the display panel comprising:

a main display area corresponding to the central area; and

a corner display area corresponding to the corner area.

15. The display apparatus of claim 14 , wherein

the second layer overlaps the central area and the side area of the first layer in a plan view, and

the second layer exposes the corner area of the first layer.

16. The display apparatus of claim 14 , wherein

the corner area comprises a first area and a second area,

the second layer overlaps the central area, the side area of the first layer, and the first area in a plan view, and

the second layer exposes the second area of the first layer.

17. The display apparatus of claim 16 , wherein the shielding member shields the second area and at least one of the central area, the side area, and the first area.

18. The display apparatus of claim 16 , wherein

the first area comprises a first line area and a second line area spaced apart from each other,

the first line area is positioned between a first side area of the side area and the second area, and

the second line area is positioned between a second side area of the side area and the second area.

19. The display apparatus of claim 18 , wherein the shielding member shields the second area and at least one of the central area, the first side area, the second side area, the first line area, and the second line area.

20. The display apparatus of claim 16 , wherein

the first area comprises line areas that extend in a first direction and are spaced apart from each other in a second direction,

the second area comprises space areas that extend in the first direction and are arranged in the second direction, and

the line areas and the space areas are arranged to alternate with each other in the second direction.

21. The display apparatus of claim 20 , wherein the shielding member comprises:

a first shielding member shielding one of the space areas; and

a second shielding member shielding another one of the space areas.

22. The display apparatus of claim 14 , wherein the shielding member comprises:

a body portion; and

a contact layer contacting the second layer.

23. The display apparatus of claim 22 , wherein the contact layer comprises metal particles.

24. The display apparatus of claim 22 , wherein the contact layer comprises:

a blocking layer arranged on the body portion; and

a conductive layer arranged on the blocking layer.

25. The display apparatus of claim 22 , wherein a surface of the body portion is flat, the surface being arranged in an opposite direction to a surface facing the display panel.

26. The display apparatus of claim 14 , wherein at least a portion of the shielding member is curved.

27. The display apparatus of claim 14 , further comprising:

a cover window overlapping the display panel in a plan view.

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

aligning a first surface of a display panel to face a cover window and bonding the cover window and the display panel to each other;

aligning a first surface of a protective film to face a second surface opposite to the first surface of the display panel and bonding the display panel to the protective film, the protective film comprising:

a first layer having:
