1. A display device in which a display area and a non-display area adjacent to the display area are defined, comprising:
a plurality of pixels in the display area;
a signal line electrically connected to the plurality of pixels;
an insulating layer on the signal line; and
a signal pad in the non-display area and electrically connected to the signal line,
wherein the signal pad comprises:
a first conductive pattern in contact with the signal line;
a second conductive pattern electrically connected to the first conductive pattern; and
a third conductive pattern located between the first conductive pattern and the second conductive pattern and electrically connected to the first conductive pattern and the second conductive pattern,
wherein the insulating layer is located between the first conductive pattern and the second conductive pattern,
wherein a contact hole overlapping the first conductive pattern when view in a plan view is defined in the insulating layer, and
wherein the second conductive pattern is in the contact hole.
