LIQUID-CRYSTAL ALIGNMENT MATERIAL AND LIQUID-CRYSTAL DISPLAY ELEMENT

摘要

A liquid-crystal alignment material is provided which can diminish the liquid-crystal orientation unevenness which occurs in the ODF mode. Also provided is a liquid-crystal display element reduced in display unevenness attributable to the liquid-crystal orientation unevenness occurring in the ODF mode. The liquid-crystal alignment material comprises a polymer obtained by reacting a tetracarboxylic dianhydride ingredient comprising a tetracarboxylic dianhydride represented by the following formula [1] with a diamine ingredient comprising a diamine compound having a carboxy or hydroxy group in the molecule. (Chemical formula 1) [1] (In the formula [1], Y1 is a C4-15 tetravalent organic group and contains a C4-8 nonaromatic cyclic hydrocarbon group.)
