Document Type and Number:
WIPO Patent Application WO/2023/120683
Kind Code:
A1
Abstract:
One purpose of the present invention is to provide a sealing agent for liquid crystal display elements, the sealing agent being excellent in terms of storage stability, adhesive properties, and low liquid crystal contamination properties. Another purpose of the present invention is to provide: a liquid crystal display element which is obtained using the above-described sealing agent for liquid crystal display elements; and a polyvalent hydrazide compound which can be used for the above-described sealing agent for liquid crystal display elements. The present invention provides a sealing agent for liquid crystal display elements, the sealing agent containing a curable resin and a thermal curing agent, wherein the thermal curing agent contains a compound which has primary amino groups and/or hydrazide groups in each molecule, with the number of the groups being 2 or more in total, while having at least either a sulfonyl group bonded to an aromatic ring or a carbonyl group bonded to an aromatic ring.
