titleOfInvention |
Liquid crystal aligning agent |
abstract |
The present invention relates to a treating agent for liquid crystal alignment, which comprises a polyamic acid compound having a reduced viscosity of from 0.05 to 5.0 dl/g (in N-methylpyrrolidone at a temperature of 30 DEG C at a concentration of 0.5 g/dl) and containing repeating units represented by the general formula ÄIÜ: <CHEM> (wherein R<1> is a tetravalent organic group constituting a tetracarboxylic acid which has an alicyclic structure having from 2 to 5 rings condensed and wherein all the carbonyl groups are directly bonded to the alicyclic structure and said carbonyl groups are not bonded to adjacent carbon atoms in the alicyclic structure, and R<2> is a bivalent organic group constituting a diamine), or a polyimide resin obtained by imidizing said polyamic acid compound, and a liquid crystal alignment film and a liquid crystal device employing it. |
