Abstract

This invention provides an alignment agent for a liquid crystal which can provide an alignment film allowing the achievement of a high and thermally stable crystal orientation and pretilt angle without the reliance on a process, such as rubbing and cleaning by an organic solvent. The alignment agent for a liquid crystal contains one or more polymers for forming an alignment film for a liquid crystal, characterized in that at least one of the polymers is a polymer which has an alkylene group having 4 to 16 carbon atoms in the main chain thereof and has a side chain having a function to enhance the pretilt angle of the liquid crystal.
