Abstract

An electronic device includes a display layer including an active area and a peripheral area adjacent to the active area. An antenna layer is disposed on the display layer and includes an antenna, an antenna line connected to one side of the antenna, and an antenna pad connected to one side of the antenna line. A cover layer is spaced apart from the antenna layer with the display layer disposed therebetween. The cover layer may at least partially overlap each of the antenna, the antenna line, and the antenna pad.
