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 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.

2. The display device of claim 1 , further comprising:
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 spaced apart from the opcning openings in a plan view.

3. The display device of claim 2 , wherein a portion of each of the plurality of sensing lines overlaps the power pattern.

4. The display device of claim 2 , 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,
wherein the plurality of second pattern portions include: 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.

5. The display device of claim 4 , wherein the openings are defined in each of the first branch pattern portion and the second branch pattern portion.

6. The display device of claim 4 , wherein the openings are defined in the first branch pattern portion and is not defined in the second branch pattern portion.

7. The display device of claim 4 , wherein the overlapping portion includes a portion of each of the plurality of second pattern portions.

8. The display device of claim 4 , 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.

9. The display device of claim 2 , 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.

10. The display device of claim 2 , wherein
the plurality of sensing lines is on the protrusion, and
each of the plurality of sensing lines extends in the second direction.

11. The display device of claim 2 , wherein each of the plurality of sensing lines that overlap the protrusion has a crooked shape.

12. The display device of claim 11 , wherein
a pitch between the plurality of openings is 40 μm, and
each of the plurality of openings has a tetragonal shape.

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

14. The display device of claim 13 , wherein the additional protrusion and the second protruding portion include a same material.

15. The display device of claim 1 , wherein the first protruding portion includes an organic material.

16. A display device, comprising:
a display panel having an active area and a peripheral area; and
an input sensor directly on the display panel,
wherein the display panel includes:
a plurality of pixels in the active area;
a protrusion in the peripheral area, the protrusion surrounding at least a portion of the active area and including a first protruding portion and a second protruding portion on the first protruding portion;
a power line configured to supply the plurality of pixels with power; and
a power pattern in the peripheral area and electrically connected to the power line, the power pattern including an overlapping portion between the first protruding portion and the second protruding portion, the overlapping portion having an opening, and
wherein the input sensor includes:
a plurality of sensing electrodes on the active area; and
a plurality of sensing lines on the peripheral area and electrically connected to the plurality of sensing electrodes, wherein each of the plurality of sensing lines that overlap the protrusion has a crooked shape corresponding to a shape of the protrusion,
wherein a portion of the protrusion extends along a first direction,
wherein portions of the plurality of sensing lines that overlap the portion of the protrusion extend along a second direction intersecting the first direction, 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 plurality of sensing lines is on the overlapping portion.

18. The display device of claim 17 , 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 the first branch pattern portion and the second branch pattern portion.

19. The display device of claim 18 , 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.

20. A display device, comprising:
a plurality of pixels in an active area;
