Abstract

A display device including a window having a light shielding region and a transmission region, a display panel disposed under the window, and an input detection sensor disposed therebetween and including first electrodes, second electrodes, first signal lines connected to one ends of the first electrodes, second signal lines connected to one ends of the second electrodes, and third signal lines connected to the other ends of the second electrodes. Each of first to n th first signal lines includes bent parts bent multiple times, resistances of the bent parts decrease in a first direction, the first to n th first signal lines are connected to the first electrodes that are arranged farther away from the bent parts in the first direction, and the bent parts of the first to n th first signal lines overlap the light shielding region.

Claims (32)

1. A display device comprising:

a window;

a display panel disposed under the window; and

an input detection sensor disposed between the window and the display panel,

wherein the input detection sensor comprises:

a first electrode extending in a first direction;

a second electrode extending in a second direction crossing the first direction;

a first signal line electrically connected to the first electrode; and

a second signal line electrically connected to the second electrode,

wherein the first signal line comprises a first-first line part, a first-second line part, and a first intermediate part between the first-first line part and the first-second line part and extending in a direction crossing the first direction and the second direction or the second direction,

the second signal line comprises a second-first line part, a second-second line part, and a second intermediate part between the second-first line part and the second-second line part and extending in a direction crossing the first direction and the second direction or the second direction,

the first-second line part is disposed farther from the second electrode than the first-first line part in the first direction,

the second-second line part is disposed farther from the second electrode than the second-first line part in the first direction,

the second-first line part and the second-second line part are disposed farther from the second electrode than the first-second line part in the first direction,

the first-first line part, the first-second line part, the second-first line part, and the second-second line part are substantially extended in a same direction,

the first-first line part and the second-first line part cross on a first imaginary line extending in the first direction, and

the first-second line part and the second-second line part cross on a second imaginary line extending in the first direction.

2. The display device of claim 1 , wherein the first intermediate part and the second intermediate part are extended in a same direction.

3. The display device of claim 1 , wherein the first signal line further comprises a first-third line part disposed farther from the second electrode than the first-second line part in the first direction and a first part bent from the first-third line part.

4. The display device of claim 3 , wherein the second signal line further comprises a second-third line part disposed farther from the second electrode than the second-second line part in the first direction and a second part bent from the second-third line part.

5. The display device of claim 4 , wherein the first part and the second part cross on a third imaginary line extending in the second direction.

6. The display device of claim 1 , wherein the second signal line further comprises a second-third line part disposed farther from the second electrode than the second-second line part in the first direction, a second-first part bent from the second-third line part and a second-second part bent from the first-first line part.

7. The display device of claim 6 , wherein the input detection sensor further comprises

a third electrode extending in the second direction; and

a third signal line electrically connected to the third electrode, and

wherein the third electrode is disposed farther from the first-first line part than the second electrode in the first direction.

8. The display device of claim 7 , wherein the third signal line comprises a third-first line part, a third-second line part, and a third intermediate part between the third-first line part and the third-second line part and extending in a direction crossing the first direction and the second direction or the second direction, and

the third-first line part is disposed farther from the second electrode than the second-first line part in the first direction.

9. The display device of claim 8 , wherein the third signal line further comprises a third-third line part disposed farther from the second electrode than the third-second line part in the first direction, a third-first part bent from the second-third line part and a third-second part bent from the first-first line part.

10. The display device of claim 9 , wherein the third-third line part, the third-first part, and the third-second part are disposed between the second-third line part and the second-second part in the first direction.

11. The display device of claim 1 , wherein line widths of the second-first line part and the second-second line part are substantially uniform.

12. The display device of claim 1 , wherein the second-first line part and the second-second line part have a substantially same line width.
