A display device includes a substrate that includes a display area that displays an image, a non-display area disposed around the display area, and an antenna area that protrudes from the non-display area, an antenna electrode disposed on one surface of the substrate in the non-display area, a feed line disposed on one surface of the substrate in the antenna area and spaced apart from the antenna electrode, a first electrode disposed on one surface of the substrate in the antenna area and the non-display area and disposed at one side of the feed line; and a second electrode disposed on one surface of the substrate in the antenna area and the non-display area and disposed on an other side of the feed line. A distance between the first electrode and the second electrode increases from one end of the feed line toward the antenna electrode.
