Abstract
In a reflective type liquid crystal display comprising a rear support plate carrying segmented reflective electrodes in a predetermined display region, a front transparent support plate carries first and second reflective coatings in a region except the region corresponding to said segmented reflective electrodes, and a transparent electrode is deposited on said front support plate and said second reflective coating. An intermediate layer of insulator material is interposed between said first and second reflective coatings. Said intermediate layer protects the first reflective coating from the influence caused by the chemical reaction between said transparent electrode and said second reflective coating.
