Abstract

This invention is a liquid-crystal-display-element sealant containing a curable resin, a thioxanthone-based polymerization initiator that can be represented by formula (1), and an amine-based sensitizer. In formula (1), n represents a number from 1 to 6; R3 represents a hydrogen atom or the like; A represents the group -O-, the group -[O(CHR2CHR1)a]y-, the group -[O(CH2)bCO]y-, or the group -[O(CH2)bCO](y-1)-[O(CHR2CHR1)a]-; R1 and R2 represent hydrogen atoms or the like; a is either 1 or 2; b is either 4 or 5; Q represents (poly)ethylene glycol, (poly)propylene glycol, (poly)butylene glycol, glycerin, trimethylolpropane, ditrimethylolpropane, pentaerythritol, dipentaerythritol, or a caprolactone polyol residue; a free hydroxyl group within Q may be esterified; x represents a number that is greater than 1 but does not exceed the number of hydroxyl groups in Q; and y represents a number from 1 to 10.

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 ...
