Reflective liquid crystal display apparatus
A reflection liquid crystal display device comprises an upper substrate; a transparent electrode formed into an electrode pattern on one side of the upper substrate; an alignment film formed on the transparent electrode; a lower substrate opposed to the upper substrate; a reflective metal electrode including Al-alloy electrodes formed into an electrode pattern and opposed to the upper substrate; a protective insulation film formed on the reflective metal electrode; an alignment film formed on the protective film; and liquid crystal filled between the upper substrate and the lower substrate. The protective insulation film has a volume resistivity of small than 1&times;109 &OHgr;-cm. The defects due to the charges stored in the protective insulation film are alleviated, and a uniform display is achieved.
