## Abstract

A display device including a window, a display panel, and an input detection sensor disposed therebetween and including a first electrode extending in a first direction, a second electrode extending in the first direction, a third electrode intersecting with the first and second electrodes while insulated therefrom, a first signal line electrically connected to an end of the first electrode, a second signal line electrically connected to an end of the second electrode, and a third signal line and a fourth signal line electrically connected to a first end and a second end of the third electrode, respectively, in which each of the first and second signal lines includes a first part and a second part extending in the first direction and disposed between the first part of the first signal line and the second part of the first signal line in a second direction crossing the first direction.

## Claims

### Claim 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 the first direction;
a third electrode intersecting with the first electrode and the second electrode, and insulated from the first electrode and the second electrode;
a first signal line electrically connected to an end of the first electrode;
a second signal line electrically connected to an end of the second electrode;
a third signal line electrically connected to a first end of the third electrode; and
a fourth signal line electrically connected to a second end of the third electrode,
wherein each of the first signal line and the second signal line comprises a first part extending in the first direction and a second part extending in the first direction, and
wherein the first part and the second part of the second signal line are disposed between the first part of the first signal line and the second part of the first signal line in a second direction crossing the first direction.
