    摘要: A liquid crystal device is constituted by a pair of electrode plates and a liquid crystal composition disposed between the electrode plates. One of the electrode plates comprises a light-transmissive substrate, a plurality of electrodes including principal electrodes and auxiliary electrodes supported on the light-transmissive substrate, a plurality of color filters disposed on the light-transmissive substrate and an insulating layer disposed on the color filters. Each auxiliary electrode is disposed between an associated principal electrode and the light-transmissive substrate so as to be electrically connected with at least a part of the associated principal electrode, and the auxiliary electrodes are disposed with spacings therebetween which are filled with the color filters and the insulating layer. The liquid crystal composition comprises at least one species of a fluorine-containing mesomorphic compound comprising a fluorocarbon terminal portion and a hydrocarbon terminal portion, the terminal portions being connected with a central core, and having smectic mesophase or latent smectic mesophase. The combination of the above specific cell structure and the specific liquid crystal composition is effective in improving display qualities (e.g., brightness and contrast) while minimizing a voltage waveform deformation.
