1. A communication terminal comprising:
- a display device that displays information on a surface on a first side thereof;
a shield plate disposed on a second side of the display device that is opposite to the first side; and
a power supply coil conductor that electromagnetically couples with the shield plate;
whereinthe power supply coil conductor is, when viewed from a normal direction of the surface on the first side of the display device, disposed so that a coil opening portion of the power supply coil conductor is at least partially positioned farther outward than an outer contour end portion of the shield plate and so that the power supply coil conductor at least partially overlaps with the shield plate, and is adjacent to the shield plate;
all portions or substantially all portions of the shield plate overlap with the second side of the display device;
the shield plate is configured and arranged to prevent electromagnetic waves emanating from the display device from entering electric circuitry in the communication terminal as noise; and
the shield plate defines and functions as an antenna that communicates with a communication partner positioned on the first side of the display device.

Abstract
A power supply coil is disposed on a rear surface of a display via a shield plate. When a current flows in the power supply coil, a magnetic flux emitted from the power supply coil traverses an opening of the shield plate. As a result, the power supply coil and the shield plate are electromagnetically coupled and the shield plate defines and functions as an antenna. Accordingly, a communication terminal communicates favorably with a smartcard, which is a device positioned on a front surface side of the display.

18. A non-transitory computer-readable medium containing a program that when run on a computer carries out a procedure for displaying information enabling a position where a sensitivity of a power supply coil conductor is highest to be seen in a display screen corresponding to a surface on a first side of a display device of a communication terminal including:
-
the display device that displays information on the surface on the first side, a shield plate disposed on a second side of the display device that is opposite from the surface on the first side; and a power supply coil conductor that electromagnetically couples with and is adjacent to the shield plate;
whereinthe power supply coil conductor is, when viewed from a normal direction of the surface on the first side of the display device, disposed so that a coil opening portion of the power supply coil conductor is at least partially positioned farther outward than an outer contour end portion of the shield plate and so that the power supply coil conductor at least partially overlaps with the shield plate, and is adjacent to the shield plate; all portions or substantially all portions of the shield plate overlap with the second side of the display device; the shield plate is configured and arranged to prevent electromagnetic waves emanating from the display device from entering electric circuitry in the communication terminal as noise; and the shield plate defines and functions as an antenna that communicates with a communication partner positioned on the first side of the display device.
