Title:
LIQUID CRYSTAL ORIENTING AGENT, LIQUID CRYSTAL ORIENTATION FILM, AND LIQUID CRYSTAL DISPLAY ELEMENT
Document Type and Number:
WIPO Patent Application WO/2015/025911
Kind Code:
A1
Abstract:
The purpose of the present invention is to provide a liquid crystal orientation film without a reduction in vertical orientation even after exposure to high temperature and light irradiation for a long time. Provided is a liquid crystal orientation film additionally capable of improving adhesiveness between a sealing agent and the liquid crystal orientation film, suppressing the incidence of display anomalies near the contours of liquid crystal display elements under high temperature and humidity, and further suppressing a reduction in the voltage retention rate. Further provided is a liquid crystal orientation agent containing a polysiloxane obtained by polycondensing an alkoxysilane having a side chain for orienting liquid crystals vertically, and a polysiloxane obtained by polycondensing an alkoxysilane having a side chain that includes a photoreactive group in its structure. However, the side chain for orienting liquid crystals vertically and the side chain that includes the photoreactive group in its structure are not present in the same polysiloxane.
