Abstract
A liquid crystal display device is structured in such a manner that plural of liquid crystal display panels each comprised of a liquid crystal layer provided between a pair of transparent substrates which have electrodes disposed on each facing inner surface, and a reflection-type polarizing film is disposed at least on the top surface of the plural liquid crystal display panel, or between the liquid crystal display panels, or on the lowest surface of the plural liquid crystal display panel. By controlling a reflection state and a transmission state through the reflection-type polarizing film with electric voltage applied on the liquid crystal layer of the liquid crystal display panel, a display which represents the opening and closing of a metallic shutter is made possible.
