Title:
LIQUID CRYSTAL ALIGNMENT FILM AND METHOD OF MANUFACTURING SAME
Document Type and Number:
WIPO Patent Application WO/2018/198434
Kind Code:
A1
Abstract:
This liquid crystal alignment film contains a side chain-type thermotropic liquid crystal polymer and a polymer of a thermotropic liquid crystal compound. The side chain-type thermotropic liquid crystal polymer has a monomer unit containing a liquid crystalline fragment side chain, and a monomer unit containing a non-liquid crystalline fragment side chain. The liquid crystal alignment film satisfies nx > nz > ny, where nx is a refractive index of the in-plane slow axis direction, ny is a refractive index of the in-plane fast axis direction, and nz is a refractive index of the thickness direction. The NZ coefficient, which is expressed as NZ = (nx – nz)/(nx – ny), is preferably 0.2-0.8.
