摘要
The present invention provides a polyimide alignment film having excellent electrical properties and excellent reliability for use in the field of electronic materials which comprises a polyimide resin produced from a polyamic acid composition comprising a polyamic acid forming a polyimide resin of a low residual voltage and a high voltage holding ratio, and a polyamic acid forming a polyimide resin of a large pre-tilt angle, blended them in the ratio of the former to the latter of 50/50 to 95/5 (weight ratio), a polyamic acid composition for providing such a polyimide aligning film and a liquid crystal display element produced from such an aligning film.
