Polymer composition and liquid crystal alignment film for in-plane-switching-type liquid crystal display element

Abstract

The present invention addresses the problem of providing a novel polymer composition for obtaining a liquid crystal alignment film for an in-plane-switching-type liquid crystal display element, the polymer composition having excellent image persistence characteristics and imparting alignment control performance with high efficiency, and a liquid crystal alignment film for an in-plane-switching-type liquid crystal display element that uses the polymer composition. The present invention solves the abovementioned problem by a polymer composition containing (A) a photosensitive side-chain macromolecule exhibiting liquid crystal properties in a predetermined temperature range, (B) polyurea, and (C) an organic solvent.

Description

technical field

[0001] The present invention relates to a novel polymer composition, a liquid crystal alignment film for a transverse electric field-driven liquid crystal display element using the same, and a method for manufacturing a substrate having the alignment film. More specifically, it relates to a new method for producing a liquid crystal display element excellent in image sticking characteristics. Background technique

[0002] Liquid crystal display devices are known as display devices that are light in weight, thin in cross-section, and low in power consumption. In recent years, they have been used in large-scale television applications, etc., and have achieved remarkable development. The liquid crystal display element is constituted, for example, by sandwiching a liquid crystal layer between a pair of transparent substrates provided with electrodes. Also, in a liquid crystal display element, an organic film containing an organic material is used as a liquid crys...
