Title:
LIQUID CRYSTAL ALIGNMENT AGENT, LIQUID CRYSTAL ALIGNMENT FILM, LIQUID CRYSTAL DISPLAY ELEMENT
Document Type and Number:
WIPO Patent Application WO/2014/034790
Kind Code:
A1
Abstract:
Provided are a liquid crystal alignment agent that contains a polymer exhibiting superior solubility, a liquid crystal alignment film, and a liquid crystal display element. The liquid crystal alignment agent is characterized by containing a polyimide precursor, which is obtained using a diamine component containing one or more compounds selected from the group consisting of the diamine compounds expressed by general formula (1) and general formula (2), and at least one polymer, which is selected from the group consisting of polyimides obtained by the imidization of the polyimide precursor (Boc represents a t-butyloxycarbonyl group. R1 represents a single bond, -CH2-, or CH2CH2-. R2 represents -O-, -COO-, -OCO-, -NHCO-, -CONH-, -NH-, -N(CH3)-, -CON(CH3)-, -N(CH3)CO-, or N(COMe)-. R3 represents a single bond or a divalent aliphatic hydrocarbon group having 1-20 carbon atoms. R4 and R5 each independently represent a hydrogen atom or an alkyl group having 1-20 carbon atoms.).
