Title:
LIQUID CRYSTAL ALIGNING AGENT, LIQUID CRYSTAL ALIGNING FILM, AND LIQUID CRYSTAL DISPLAY ELEMENT
Document Type and Number:
WIPO Patent Application WO/2018/070507
Kind Code:
A1
Abstract:
The present invention pertains to a polymer composition containing a copolymer which is obtained from a monomer mixture (A) including a monomer (A-1) and a monomer (A-2), wherein the monomer (A-1) is a monomer having a single cinnamoyl moiety, 2-4 benzene rings which do not constitute the cinnamoyl moiety, and a polymerizable group, and the monomer (A-2) is a monomer having a single cinnamoyl moiety, a benzene ring which does not constitute the cinnamoyl moiety, and a polymerizable group (the cinnamoyl moiety and the benzene ring may have a substituent). The present invention also pertains to a method for producing a substrate having a liquid crystal aligning film, comprising a step for applying the composition to a substrate having an electrically conductive film for horizontal electric field drive to form a coating film, a step for irradiating the obtained coating film with polarized ultraviolet light, and a step for heating the obtained coating film. The liquid crystal aligning agent which employs the polymer composition according to the present invention is highly efficient and is imparted with an alignment control capability, has superior image burn-in characteristics, and can provide a horizontal electric field drive-type liquid crystal display element.
