  • Patent number: 10147998
    Abstract: An antenna of a communication terminal is disposed on a side on which a bottom surface of a reflective plate, which is included in a display, is present. When the reflective plate is irradiated by an LED light source, the antenna cannot be seen from the side on which a display screen of the display is disposed. Accordingly, an antenna coil of the antenna does not need transparent electrodes and can be made of various materials each having a high conductivity. Therefore, the antenna has high sensitivity, low manufacturing cost, and very efficiently performs near field communication with an external device located on the display screen side of the display.
