1. A display device, comprising:
a display panel including a display region on which a pixel is disposed and a non-display region at least partially surrounding the display region;
an input sensor disposed on the display panel and configured to detect an electromagnetically induced current; and
a conductive layer disposed below the display panel and at least partially overlapping the display region,
wherein the conductive layer includes a first unit pattern, and
wherein the first unit pattern includes:
a first extension part extending in a first direction; and
a plurality of second extension parts that extend from the first extension part in a second direction intersecting the first direction, the plurality of second extension parts being disposed on one side of the first extension part,
wherein the input sensor includes:
a first electrode;
a second electrode that extends in a direction intersecting the first electrode and is capacitively coupled to the first electrode;
a third electrode that detects the electromagnetically induced current;
a fourth electrode that extends a direction intersecting the third electrode and detects the electromagnetically induced current;
a first signal line connected to a first end of the first electrode;
a second signal line connected to a first end of the second electrode;
a 1-1st signal line connected to a first end of the third electrode and overlapped with the non-display region;
a 1-2nd signal line of connected to a second end of the third electrode and overlapped with the non-display region; and
a third signal line connected to a first end of the fourth electrode,
wherein a first signal is applied to the 1-1st signal line when a second signal is applied to the 1-2nd signal line at a first time,
wherein the first signal is different from the second signal, and
wherein the first end of the third electrode and the second end of the third electrode are positioned oppositely in a direction in which the third electrode extends.
