ABSTRACT:
A liquid-crystal display for use in small-sized transceivers is provided. This display includes a signal processing circuit processing a radio signal received by an antenna, a liquid-crystal driver converting an output signal from the signal processing circuit into a display control signal, a liquid-crystal plate responsive to the display control signal from liquid-crystal driver to display information thereon carried by the radio signal, an electroluminescence plate disposed between the liquid-crystal plate and the liquid-crystal driver, illuminating a bottom area of the liquid-crystal plate opposite to the display area, and a conductive shield member attached to the bottom area of the electroluminescence plate, blocking conductive coupling of the liquid-crystal plate and the liquid-crystal driver for screening the antenna from noise interfering with radio reception.
