Abstract

A display device includes: a base layer having a first area and a second area adjacent to the first area; a plurality of pixels on the first area of the base layer; a power line configured to supply the plurality of pixels with power; a power pattern on the second area and electrically connected to the power line; and a protrusion on the second area, the protrusion surrounding at least a portion of the first area and including a first protruding portion and a second protruding portion on the first protruding portion, wherein the power pattern includes an overlapping portion between the first protruding portion and the second protruding portion, the overlapping portion having an opening.

Claims (51)

1. A display device, comprising:

a base layer having a first area, a second area adjacent to the first area, and comprising a bending area;

a plurality of pixels on the first area of the base layer;

a power line configured to supply the plurality of pixels with power;

a power pattern on the second area and electrically connected to the power line and overlapping the bending area;

a protrusion on the second area, the protrusion surrounding at least a portion of the first area and including a first protruding portion and a second protruding portion on the first protruding portion;

an encapsulation layer on the plurality of pixels;

a plurality of sensing electrodes on the first area and directly on the encapsulation layer; and

a plurality of sensing lines on the second area and electrically connected to the plurality of sensing electrodes,

wherein portions of the plurality of sensing lines located on the bending area all overlap with the power pattern.

2. The display device of claim 1 , wherein the power pattern includes an overlapping portion between the first protruding portion and the second protruding portion, and

wherein the plurality of sensing lines is located on the second protruding portion.

3. The display device of claim 2 , wherein the overlapping portion has openings,

wherein a portion of the protrusion extends along a first direction,

wherein the openings are arranged along the first direction, and

wherein the bending area extends along the first direction and is spaced apart from the first area in a second direction intersecting the first direction.

4. The display device of claim 3 , wherein the plurality of sensing lines is spaced apart from the openings in a plan view.

5. The display device of claim 3 , wherein the power pattern includes: a first pattern portion that extends along the first direction; and a plurality of second pattern portions that protrude along the second direction from the first pattern portion, and

wherein the plurality of second pattern portions includes: a first branch pattern portion that overlaps at least portions of the plurality of sensing lines; and a second branch pattern portion that does not overlap the plurality of sensing lines.

6. The display device of claim 5 , wherein the openings are defined in each of the first branch pattern portion and the second branch pattern portion.

7. The display device of claim 5 , wherein the openings are defined in the first branch pattern portion and is not defined in the second branch pattern portion.

8. The display device of claim 5 , wherein the overlapping portion includes a portion of each of the plurality of second pattern portions.

9. The display device of claim 5 , wherein each of the plurality of second pattern portions has a width of equal to or less than 1,300 micrometers (μm) in the first direction.

10. The display device of claim 3 , wherein a minimum distance between the openings and the plurality of sensing lines is equal to or greater than 58.4 μm in a plan view.

11. The display device of claim 3 , wherein each of the plurality of sensing lines extends in the second direction.

12. The display device of claim 1 , wherein each of the plurality of sensing lines that overlap the protrusion has a crooked shape.

13. The display device of claim 1 , further comprising an additional protrusion on the second area and is closer than the protrusion to the first area,

wherein a portion of the power pattern is below the additional protrusion, and

wherein the additional protrusion and the second protruding portion include a same material.

14. A display device, comprising:

a base layer having a first area, a second area adjacent to the first area, and comprising a bending area;

a plurality of pixels on the first area of the base layer;

a power line configured to supply the plurality of pixels with power;

a power pattern on the second area and electrically connected to the power line and overlapping the bending area;

a protrusion on the second area, the protrusion surrounding at least a portion of the first area and including a first protruding portion, a second protruding portion on the first protruding portion, and a third protruding portion on the second protruding portion;

an encapsulation layer on the plurality of pixels;

a plurality of sensing electrodes on the first area and directly on the encapsulation layer; and

a plurality of sensing lines on the second area and electrically connected to the plurality of sensing electrodes,

wherein the plurality of sensing lines is located on the third protruding portion, and

wherein portions of the plurality of sensing lines located on the bending area all overlap with the power pattern.

15. The display device of claim 14 , wherein a portion of the protrusion extends along a first direction, and

wherein portions of the plurality of sensing lines that overlap the portion of the protrusion extend along a second direction intersecting the first direction.

16. The display device of claim 15 , wherein the power pattern includes an overlapping portion between the first protruding portion and the second protruding portion, the overlapping portion having an opening, and

wherein the plurality of sensing lines is spaced apart from the opening in the first direction.

17. The display device of claim 16 , wherein

the power pattern includes a first branch pattern portion and a second branch pattern portion that extend along the second direction and that are between the first protruding portion and the second protruding portion, and

the opening is provided in at least one selected from among the first branch pattern portion and the second branch pattern portion.

18. The display device of claim 17 , wherein

at least portions of the plurality of sensing lines are on the first branch pattern portion, and

the opening is defined in the first branch pattern portion.

19. The display device of claim 14 , wherein each of the first protruding portion, the second protruding portion, and a third protruding portion includes an organic material.
