Title:
METHOD FOR PRODUCING SUBSTRATE HAVING LIQUID CRYSTAL ORIENTATION FILM FOR IN-PLANE-SWITCHING LIQUID-CRYSTAL DISPLAY ELEMENT
Document Type and Number:
WIPO Patent Application WO/2014/185413
Kind Code:
A1
Abstract:
The present invention provides an in-plane-switching liquid-crystal display element having superior burn-in properties and to which an orientation control ability has been imparted at a high efficiency. The present invention achieves same by means of a method that is for producing a substrate having a liquid crystal orientation film for an in-plane-switching liquid-crystal display element to which an orientation control ability has been imparted and that obtains the liquid crystal orientation film by means of having: [I] a step for forming a coating film by applying onto a substrate having a conductive film for in-plane switching a polymer composition containing (A) a photosensitive side-chain polymer exhibiting liquid crystal properties in a predetermined temperature range and (B) an organic solvent; [II] a step for radiating polarized ultraviolet rays at the coating film obtained in [I]; [III] a step for heating the coating film obtained in [II]; and [IV] a step for cooling the coating film heated in [III] to a temperature less than the glass transition temperature of the surface of the coating film, and then re-heating to a temperature that is at least the glass transition temperature.
