Title:
SILICON-BASED LIQUID CRYSTAL ALIGNING AGENT, LIQUID CRYSTAL ALIGNMENT FILM, AND LIQUID CRYSTAL DISPLAY ELEMENT
Document Type and Number:
WIPO Patent Application WO/2012/165354
Kind Code:
A1
Abstract:
Provided is a liquid crystal aligning agent capable of forming a liquid crystal alignment film in which the response rate after UV irradiation can be increased without decreasing the vertical orientation force, even for a liquid crystal display element obtained by using a liquid crystal including no polymerizable compound and a mode that treats in the same manner as the PSA mode to increase the response rate after UV irradiation. The liquid crystal aligning agent is characterized by including a polysiloxane (A) obtained by polycondensation of alkoxysilanes including the alkoxysilane represented by formula (1) and the alkoxysilane represented by formula (3). R1Si(OR2)3 (1) (where, R1 represents a structure according to formula (2), and R2 represents a C1-5 alkyl group) (2) (where, Y1 represents a single bond or the like, Y2 represents a single bond or the like, Y3 represents a single bond or the like, Y4 represents a divalent cyclic group or the like selected from a benzene ring, a cyclohexyl ring, or a hetero ring, Y5 represents a divalent cyclic group or the like selected from the group consisting of a benzene ring, a cyclohexyl ring, and a hetero ring, n represents an integer from 0 to 4, and Y6 represents a hydrogen atom or the like) R3Si(OR4)3 (3) (where, R3 represents a C1-30 alkyl group substituted with an acryl group or the like, and R4 represents a C1-5 alkyl group).
