Abstract

The object of this invention is to provide the sealing compound for liquid crystal display elements which is excellent in photocurability and can suppress liquid crystal contamination. Moreover, the object of this invention is to provide the vertical conduction material and liquid crystal display element which were created using this sealing compound for liquid crystal display elements. The present invention is a sealant for liquid crystal display elements containing a curable resin, a thioxanthone-based polymerization initiator, and an amine-based sensitizer represented by the following formula (1), In the formula (1), z represents an integer of 1 or more, and P is (poly)ethylene glycol, (poly)propylene glycol, (poly)butylene glycol, glycerol, trimethylol propane, bis(trimethylol) ) residues of propane, pentaerythritol, dipentaerythritol, or caprolactone polyols.

Description

technical field [0001] The present invention relates to a sealing compound for liquid crystal display elements which is excellent in photocurability and can suppress liquid crystal contamination. Moreover, this invention relates to the vertical conduction material and liquid crystal display element which were created using this sealing compound for liquid crystal display elements. Background technique [0002] In recent years, as a method of manufacturing liquid crystal display elements such as liquid crystal display units, from the viewpoints of shortening takt time and optimizing the amount of liquid crystal used, the method disclosed in Patent Document 1 and Patent Document 2 using a curable resin containing A liquid crystal dropping method called a dropping process, using a photothermal combination curing type sealant of a photopolymerization initiator and a thermosetting agent. [0003] In the dropping process, first, a rectangular seal pattern is formed on one of the ...
