Abstract

A display device includes a display panel including a display layer having light-emitting elements on the substrate, and a sensor electrode layer on the display layer. The sensor electrode layer includes sensor electrodes in a sensor area, sensor lines electrically connected to the sensor electrodes and a first conductive pattern spaced apart from the sensor lines and sensor electrodes. The sensor lines and the first conductive pattern are in a sensor peripheral area adjacent to the sensor area. The first conductive pattern is an antenna.
