Reflective liquid crystal display apparatus

A reflective liquid crystal display apparatus comprising:

• an upper substrate, a transparent electrode formed into an electrode pattern on one side of said upper substrate, an alignment film on the side of the upper substrate formed on the surface of said transparent electrode, a lower substrate disposed opposite to said upper substrate, a metal reflection electrode containing a film having at least Al as the main ingredient formed into an electrode pattern on the surface of said lower substrate opposite to said upper substrate, an insulating film for electrode protection formed on the surface of said metal reflection electrode, an alignment film on the side of the lower substrate formed on the surface of said insulating film for electrode protection, and liquid crystal filled in the space formed between said upper substrate and said lower substrate, wherein:
• the volume resistivity of said insulating film for electrode protection is adjusted to 1×109 Ωcm or smaller as means for preventing charge storage in said insulating film for electrode protection,
• said metal reflection electrode is a dual-layer film laminate of Ti and an Al alloy, and
• said insulating film for electrode protection is an inorganic insulating film.
