Abstract
The liquid crystal display device of the present invention comprises at least one aramide-silicone-multiblock copolymer having the repeating unit represented by the following formula as an alignment layer material: ##STR1## A desired pretilt angle can be obtained by altering the content of polysiloxane in the aramide-silicone-multiblock copolymer and the pretilt angle is nearly uniform irrespective of an annealing temperature and a rubbing strength.
