Abstract

A liquid-crystal alignment material which is reduced in film wear in rubbing and can give a satisfactory liquid-crystal alignment film; and a liquid-crystal display element reduced in display failures attributable to film wear. The liquid-crystal alignment material comprises at least one polymer selected between a polyamic acid obtained by reacting and polymerizing a diamine ingredient with a tetracarboxylic dianhydride ingredient and a polyimide obtained by subjecting the polyamic acid to dehydrating cyclization, and is characterized in that the diamine ingredient comprises a diamine represented by the following general formula [1]. The liquid-crystal display element has a liquid-crystal alignment film obtained from this liquid-crystal alignment material. (In the formula [1], n and m each is an integer of 0-4; and R is at least one organic group selected from the group consisting of hydroxy, C1-3 alkyl, C1-3 alkoxy, C2-3 alkenyl, carboxy, cyano, and halogeno, provided that when n+m is 2 or larger, then the R's may be the same or different.)
