Reflective liquid crystal displays having multilayer rear substrates

摘要

There is provided a reflective liquid crystal cell formed of a liquid crystal material disposed between first and second substrates. The first substrate is optically transparent and is formed with a coating of optically transparent and electrically conductive material on the side facing the liquid crystal material. The second substrate is formed with a plurality of coatings on the side facing the liquid crystal material. These coatings include in sequence a layer of metallic reflective material, a layer of electrically insulating material, a layer of na optically transparent and conductive material and a liquid crystal alignment layer.
