Fail-Safe Type Liquid Crystal Mirror for Automobiles

A new type of liquid crystal anti-glare mirror which satisfies the fail-safe condition, i.e. when electrical power supply of a mirror control is broken, the non-anti-glaring normal mode is always maintained has been developed. While, a conventional liquid crystal anti-glare mirror does not satisfy this fail-safe condition. The development of our new type mirror was supported by our improved surface treatment technique for the perpendicular alignments.
