Abstract: A display device comprises first scan line and a second scan line that extend in a first direction, a third scan line extending in a second direction intersecting the first direction, the third scan line intersecting the first scan line and the second scan line, and an insulating layer including a scan contact hole disposed between the first scan line and the third scan line, and a recess pattern disposed between the second scan line and the third scan line. The scan contact hole passes through the insulating layer in. The first scan line and the third scan line are in electrical contact with each other by the scan contact hole. The recess pattern includes a shape recessed from an upper surface to a lower surface of the insulating layer. The second scan line and the third scan line are electrically insulated from each other.
