Document Type and Number:
WIPO Patent Application WO/2019/230709
Kind Code:
A1
Abstract:
The purpose of the present invention is to provide a sealant for a liquid crystal display element, the sealant having excellent adhesiveness, moisture permeation prevention, and liquid crystal contamination resistance. Another purpose of the present invention is to provide a vertical conduction material and a liquid crystal display element, which are obtained using the sealant for a liquid crystal display element. The present invention is: (A) a sealant for a liquid crystal display element, the sealant containing a curable resin and a radical polymerization initiator, wherein the curable resin is a (meth)acrylic compound having a hydrogen-bonding functional group value of 0.0030 mol/g or greater and a molecular weight of 500-1200, not having an epoxy group, and having three or more aromatic rings per molecule; and/or (B) a sealant for a liquid crystal display element, the sealant containing a partial (meth)acrylic modified epoxy resin that has a hydrogen-bonding functional group value of 0.0030 mol/g or greater and a molecular weight of 500-1200, and having three or more aromatic rings per molecule.
