REFLECTIVE LCD WITH CONDUTING POLYPYRROLE

摘要

PURPOSE: A reflective liquid crystal display device is to include a polypyrrole film capable of replacing an electrode layer, a light absorbing layer and a liquid crystal alignment layer of the liquid crystal display device. CONSTITUTION: The liquid crystal display device includes an upper glass substrate(2), a lower glass substrate(12) opposed to the upper glass substrate, a transparent electrode film(4) applied on an inner surface of the upper glass substrate, and a liquid crystal alignment film(6) formed on the transparent electrode film, an electrical conductive polypyrrole film(10) formed on an inner surface of the lower glass substrate, and a liquid crystal layer(8) disposed between the electrical conductive polypyrrole film and the liquid crystal alignment film. If the liquid crystal in the liquid crystal layer is in a planar state, the polypyrrole film reflects a visible ray of a specific wavelength, so that the reflected color is viewable.
