Abstract
A liquid crystal device having a cell structure including two base plates each provided with transparent electrodes and a the ferroelectric liquid crystal disposed between the base plates. Adjacent to the transparent electrodes, auxiliary electrodes ordinarily composed of a metal are disposed so as to lower the resistance of the transparent electrodes. Insulating films are also disposed alternately with the auxiliary electrodes so as to provide a flat surface, whereby generally flat surfaces contacting the ferroelectric liquid crystal are formed to provide a uniform monodomain free of alignment defects. Thus, proper driving characteristics of ferroelectric liquid crystal device are provided.
