    Abstract: A display device is disclosed. The display device includes a display panel configured to display an image, and a printed circuit board electrically connected to the display panel and disposed at a back surface of the display panel. The printed circuit board includes an insulating layer, a first metal layer disposed at one surface of the insulating layer, pads including a first pad disposed on the first metal layer while being disposed inside a mounting area where an integrated circuit is mounted, and second pads disposed around the first pad, and a groove provided to extend from an inside of the mounting area to an outside of the mounting area.
