Document Type and Number:
Japanese Patent JP5061709
Kind Code:
B2
Abstract:
An aligning film hard to be reduced by rubbing treatment is sought. An aligning film composition and an aligning film making the aligning characterist appear uniformly are sought. An aligning film and a liquid crystal display element fabricated with a high yield rate are sought. Therefore, this present invention provides a liquid crystal aligning film composition including at least one group chosen from groups composed of polyeater-polyamide acid (A1) and its imidization compound ''polyeater-polyimide (A2)''. The polyeater-polyamide acid (A1) is obtained by at least using polyhydroxy compound (a1), diamine (a2) and a compound (a3) having at least two acid anhydride radicals.
