Document Type and Number:
WIPO Patent Application WO/2017/170951
Kind Code:
A1
Abstract:
[Problem] To provide a polymer composition for a liquid crystal alignment film that can align a polymerizable liquid crystal composition when obtaining a highly dichroic polarizing element. [Solution] Provided is a polymer composition containing (A) a photosensitive side-chain polymer that exhibits liquid crystal properties within a predetermined temperature range, and (B) a dichroic pigment and an organic solvent. On a substrate having a liquid crystal alignment film formed from the polymer composition, the alignment film is coated with a polymerizable liquid crystal composition, after which the polymerizable liquid crystal composition is heated and dried and then irradiated with ultraviolet rays as necessary, such that a highly dichroic polarizing element can be yielded.
