DIAMINE COMPOUND, LIQUID CRYSTAL ALIGNING AGENT AND LIQUID CRYSTAL DISPLAY ELEMENT
Document Type and Number:
WIPO Patent Application WO/2011/105576
Kind Code:
A1
Abstract:
Disclosed are: a liquid crystal aligning agent which is capable of providing a liquid crystal alignment film that has high rubbing resistance, good liquid crystal aligning properties and high voltage holding ratio; a polymer for the liquid crystal aligning agent; and a novel diamine compound that can be a starting material of the polymer. Specifically disclosed are: a diamine compound represented by formula (1); a polymer such as a polyamic acid or a polyimide, which is synthesized using the diamine compound as a starting material; a liquid crystal aligning agent which contains the polymer; a liquid crystal alignment film; and a liquid crystal display element. In formula (1), R1 represents -O-, -COO- or the like; R2 represents a linear or branched alkylene group having 1-20 carbon atoms; and R3 represents -CH2-, -O- or the like.
