Liquid crystal display for reflection operation with a guest-host liquid crystal layer and method of making

摘要

A liquid crystal display for reflection operation with a guest- host liquid crystal layer disposed between two cell plates and respective front and rear electrodes, and with a diffusely divergent reflector integrated in the interior of the cell, at least the front side of the cell plate and the front electrode being transparent. The rear electrode and its supply comprise thick layers, and the reflector consists of metal parts insulated against one another and applied to the rear electrode and to the inner surface of the rear cell plate. Also disclosed is a method of producing a liquid crystal display including the steps of printing in a first screen printing process a thick layer having metal parts and a binder and having the configuration of the back electrode and its supply line on the inner surface of the rear cell plate, applying in the subsequent visual region in a second screen printing process a reflector layer with mutually insulated metal parts and a binder to the thick layer and to the inner face of the rear cell plate, printing in a third screen printing process a glass solder impression on the edges of the inner surface of the rear cell plate, mounting a front cell plate having a transparent front electrode disposed on its inner face on the glass solder impression, glass soldering the individual layers formed by the first, second and third printing processes and the front cell plate, and curing the individual layers and the front cell plate.
