LIQUID CRYSTAL ALIGNING AGENT FOR PHASE DIFFERENCE FILM LIQUID CRYSTAL ALIGNMENT FILM FOR PHASE DIFFERENCE FILM THE PHASE DIFFERENCE FILM AND ITS MANUFACTURING METHOD

摘要

It is an object of the present invention to provide a liquid crystal aligning agent capable of forming a liquid crystal alignment film for a phase difference film which is capable of photoexposing even by irradiation with a small amount of radiation and which does not require a heating step during irradiation and after irradiation and a liquid crystal alignment film for this phase difference film And which is excellent in liquid crystal alignability and thermal stability, and a process for producing the same. [MEANS FOR SOLVING PROBLEMS] The present invention relates to a liquid crystal aligning agent for a retardation film containing cellulose containing a group having [A] cinnamic acid structure. Further, [A] cellulose is preferably represented by the following formula (1).
