Liquid crystal display with mutually oriented and dispersed birefringent polymer and liquid crystal and random oriented twist alignment

摘要

On the substrate (108) are made reflecting type picture element electrodes (107), of Cr, and on substrate 101 are made transference picture element electrodes (102), of ITO. On both substrates (108, 101) parallel alignment films (106, 103), consisting of polyimide alignment films, are each made, but rubbing treatment is not administered. Between the substrates (108. 101) polymer dispersion liquid crystal, in which liquid crystal (105) and polymer (104) are in a state of mutual orientation dispersion, is placed. Liquid crystal (105) is parallel oriented randomly near the substrate surfaces, and twisted approximately 90 between the substrates (101, 108). Also, the orientation domains from the liquid crystal random orientation are evenly multidomained at the level of approximately 1-3 m. Because they are randomly oriented in this way, directivity of scatter is improved, and operation voltage is decreased.
