Title:
METHOD FOR PRODUCING SUBSTRATE HAVING LIQUID CRYSTAL ORIENTATION MEMBRANE FOR USE IN IN-PLANE-SWITCHING LIQUID CRYSTAL DISPLAY ELEMENT
Document Type and Number:
WIPO Patent Application WO/2014/185411
Kind Code:
A1
Abstract:
The present invention provides an in-plane-switching liquid crystal display element which exhibits excellent burn-in properties and efficiently controls orientation. To this end, the present invention provides a polymer composition containing: (A) a photosensitive side-chain polymer which exhibits liquid-crystal properties within a prescribed temperature range; (B) an amine compound intramolecularly having one primary amino group and a nitrogen-containing aromatic heterocyclic ring, the primary amino group being one which bonds to an aliphatic hydrocarbon group or a non-aromatic-ring hydrocarbon group; and (C) an organic solvent. Specifically, the present invention provides a method which makes it possible to produce a substrate having a liquid crystal orientation membrane, and to obtain a liquid crystal orientation membrane for use in an in-plane-switching liquid crystal display element having the ability to control orientation, by having the following steps: [I] a step for forming a film by applying said composition onto a substrate having a conductive film for in-plane switching; [II] a step for irradiating the film obtained in [I] with polarized ultraviolet rays; and [III] a step for heating the film obtained in [II].
