  • Patent number: 4614406
    Abstract: A liquid crystal display device, which comprises a light transmissive carrier made as a foundation piece for assembly. A display section and a retainer covering the front side of the display section are positioned and locked to the front side of the carrier. An electric circuit section is positioned and locked to the rear side of the carrier. Thus, the device can be accurately and easily assembled. Also, uncomfortable noise due to external vibrations can be eliminated. To enhance the reliability of recognition, a reflector is provided on the rear side of the light transmissive carrier while a semi-transparent reflector is provided between the display section and carrier. The retainer is electrically connected to a ground potential part of the electric circuit section to prevent adverse effect of an electrostatic charging phenomenon that might otherwise result.
