1. A display device comprising:
a first conductive layer including a signal line, which includes a pad contact part and a line part having a smaller width than the pad contact part along a first direction and extending from the pad contact part in a second direction that intersects the first direction, and a first non-contact pattern, which is spaced apart from the pad contact part, on a first side along the first direction;
an insulating layer on the first conductive layer and including a contact hole that partially exposes the first conductive layer;
a second conductive layer on the insulating layer and including a first pad electrode, which is electrically connected to the first conductive layer through the contact hole,
wherein the first pad electrode overlaps with the pad contact part and the first non-contact pattern,
wherein the display device further comprises a third conductive layer on the second conductive layer and including a second pad electrode, which is electrically connected to the first pad electrode,
wherein the first pad electrode includes a main pad electrode part, which is connected to the pad contact part, and a sub-pad electrode part, which is spaced apart from the main pad electrode pad by a gap.
