Abstract:
1. A liquid crystal alignment solution, comprising at least one polymer selected from the group consisting of a polyamide acid-polyamide acid polymer represented by formula (A), a polyimide-polyamide acid polymer represented by formula (B) and a polyimide-polyimide polymer represented by formula (C), wherein T m<n; p<q; r<s; D in the formulae (3) and (4), R X is —O—, —SO— or —SO a and b are each independently an integer from 0 to 4; and c and d are each independently an integer from 0 to 3; in the formulae (5) and (6), R X is —O—, —S—, —SO—, —SO Z is a divalent organic group, —O—, —S—, —SO—, —SO a, b, e and f are each independently an integer from 0 to 4; and c and d are each independently an integer from 0 to 3; in the formulae (9)-(11) and (15), R R R X′ and Y′ are each independently a divalent group selected from the group consisting of —O—, —NH—, —S—, —CO—, —COO—, —NHCO— and —CONH—; A is a divalent group selected from the group consisting of —O—, —NH—, —S—, —CO—, —COO—, —OCO—, —NHCO— and —CONH—; and a′ and b′ are each independently an integer larger than or equal to 1.
