Title:
SEALING AGENT FOR LIQUID CRYSTAL DISPLAY ELEMENTS, VERTICAL CONDUCTION MATERIAL, AND LIQUID CRYSTAL DISPLAY ELEMENT
Document Type and Number:
WIPO Patent Application WO/2019/013154
Kind Code:
A1
Abstract:
The purpose of the present invention is to provide a sealing agent for liquid crystal display elements which exhibits excellent application properties, curability, and low liquid crystal staining properties. Another purpose of the present invention is to provide a vertical conduction material and a liquid crystal display element which are obtained by using the sealing agent for liquid crystal display elements. This sealing agent for liquid crystal display elements includes a curable resin and a polymerization initiator. The curable resin includes: a partially (meth)acrylic-modified novolac-type epoxy resin (A); a partially (meth)acrylic-modified non-novolac-type epoxy resin (B); and a non-novolac-type epoxy (meth)acrylate (C). The content of the partially (meth)acrylic-modified novolac-type epoxy resin (A) is at least 3 but not more than 9 parts by weight in 100 parts by weight of the curable resin. The content of the partially (meth)acrylic-modified non-novolac-type epoxy resin (B) is not more than 25 parts by weight in 100 parts by weight of the curable resin. The ratio of the partially (meth)acrylic-modified non-novolac-type epoxy resin (B) to the partially (meth)acrylic-modified novolac-type epoxy resin (A) is 1 or higher. The content of the non-novolac-type epoxy (meth)acrylate (C) is at least 10 but not more than 45 parts by weight in 100 parts by weight of the curable resin. The partially (meth)acrylic-modified novolac-type epoxy resin (A) has a weight average molecular weight in the range of 700-2000 inclusive.
