Conductive liquid crystal polymer composites and a process for the preparation thereof are disclosed, as well as the preparation of liquid crystal alignment layers for liquid crystal displays and a process for the preparation thereof. Also, the disclosure relates to the preparation of conductive liquid crystalline polymer composites with an excellent processability and stability, and a process for the preparation of conductive alignment layers that reduce the static charge during the fabrication of the displays.

Conductive liquid crystal alignment layers and process for the

Conductive polymers having repeating units of formula (II) ##STR1## formed by chemical or electrochemical oxidation of aniline derivatives of formula (I) ##STR2## wherein R.sub.1 denotes --(CH.sub.2).sub.n --; n is an integer between 2 and 12; R.sub.2, R.sub.3, R.sub.4 and R.sub.5 denote hydrogens or one or two of them can be a halogen atom, methyl, methoxy or nitro groups; and X denotes hydrogen an alkali metal ion, an ammonium ion, an alkyl ammonium ion or an anilinium ion. The conductive polymers have excellent stability toward electrochemical redox cyclization and good processibility.
