Abstract
A liquid crystal display, and process of manufacture therefor, emloying an integrated reflector internal to the liquid crystal cell, and consisting of a guest-host liquid crystal layer sandwiched between two cell plates and located between front and rear electrodes. At least the front electrode is composed of segments and parts of the reflector and/or rear electrode that lie opposite the conduction paths leading to these segments are at an electrical potential whose difference from the potential of the conduction paths is smaller than the threshold voltage of the liquid crystal layer used.
