Abstract

A display device includes a substrate including a display area in which an image is displayed, a non-display area disposed around the display area, and an antenna area protruding from the non-display area. The display device further includes an antenna electrode disposed on one surface of the substrate in the non-display area, a first electrode disposed on the one surface of the substrate in the antenna area and spaced apart from the antenna electrode, and a feed line disposed on another surface of the substrate, which opposes the one surface, in the antenna area. The antenna electrode is connected to the feed line through a hole penetrating the substrate.
