Abstract

The invention relates to a liquid crystal orientation agent and various applications thereof, a polymer and a producing method thereof. Liquid crystal orientation film with wide vision, good quality, good afterimage and burning-in is provided. Liquid crystal orientation agents capable of forming liquid crystal orientation film through light orientation method are provided. The liquid crystal orientation agent is used for producing phase difference films which has good contrast among boundaries of adjacent areas under different polarization states and has a stable polarization state. The liquid crystal orientation agent comprises polymer expressed in the following formula (1), wherein R is respectively alkyl with 1-4 carbon atoms, hydroxyl, halogen atom or cyan; a is respectively an integer from 0 to 4; * represents a connecting key.

Description

technical field

[0001] The present invention relates to a liquid crystal aligning agent, a liquid crystal aligning film, a liquid crystal display element, a method for forming a retardation film, a retardation film, a liquid crystal display element, a polymer, and a method for producing the polymer. More specifically, it is related with the liquid crystal aligning agent used suitably when forming the liquid crystal aligning film used for a transverse electric field type liquid crystal display element or a retardation film by the photo-alignment method especially. Background technique

[0002] In a liquid crystal display element, in order to align liquid crystal molecules in a predetermined direction with respect to a substrate surface, a liquid crystal aligning film is provided on the substrate surface. The liquid crystal alignment film is usually formed by polishing the surface of the organic film formed on the surface of the substrate in a certain direction (polishing meth...
