Abstract
Reflective mode dynamic scattering displays are disclosed which operate under dc excitation for extremely long hours with excellent contrast. These displays are the results of a combination of a high reflectivity cathode, obtained by the use of silver mirror electrodes, with a redox doped ester liquid crystal in an otherwise conventional liquid crystal cell arrangement.
