ABSTRACT:
A liquid crystal orientation film, which is formed of a liquid crystal polymer, having a satisfactory orientation property is obtained by a method for manufacturing a liquid crystal orientation film, comprising the steps; coating a polymerizable liquid crystal monomer on an orientation substrate; orienting said polymerizable liquid crystal monomer in a state of liquid crystal; polymerizing said polymerizable liquid crystal monomer to form a liquid crystal orientation layer (1); coating a liquid crystal polymer on said liquid crystal orientation layer (1); and orienting said liquid crystal polymer in a state of liquid crystal to form a liquid crystal orientation layer (2).
