A display device includes sensor electrodes for sensing a touch. The sensor electrodes may also be used as an antenna. A display circuit board of the display device includes a radio signal connection unit for providing touch sensing signals and radio reception signals of the sensor electrodes to a touch driving circuit and an antenna driving circuit. Therefore, the display device not only senses a user's touch using the sensor electrodes but also conducts mobile communication using the sensor electrodes. For example, sensor electrodes for sensing a touch may also be used as an antenna.
