POLYIMIDE PRECURSOR, POLYIMIDE, AND LIQUID-CRYSTAL ALIGNMENT MATERIAL

摘要

To provide a novel diamine which is useful as the starting material of a novel polyimide precursor or polyimide which can provide a liquid crystal alignment film having a low volume resistivity, a liquid crystal aligning agent containing these polymers, and a liquid crystal alignment film. The novel diamine is a compound represented by any one of the following formulae (A) to (C):
