Problems solved by technology
[0005] However, if a liquid crystal display element with a narrow bezel design is manufactured by a dropping process, there are places where light does not reach the sealing portion due to the black matrix, so there may be a portion where photocuring is not sufficiently performed, and the The cured sealant is in contact with the liquid crystal
In this case, there are the following problems: sometimes the liquid crystal is inserted into the sealant, and the seal is broken, causing the liquid crystal to leak out; the uncured sealant dissolves into the liquid crystal, and the liquid crystal is contaminated.

Abstract
One purpose of the invention is to provide a sealing agent for liquid crystal display elements, which is capable of suppressing penetration of liquid crystals into the sealing agent and contaminationof liquid crystals by the sealing agent. Another purpose of the invention is to provide: a vertically conducting material which is obtained using this sealing agent for liquid crystal display elements; and a liquid crystal display element. The invention is a sealing agent for liquid crystal display elements, which contains a curable resin and a polymerization initiator and / or a thermal curing agent, and wherein the curable resin contains a compound that has a polymerizable functional group and a structure represented by formula (1).
Description
technical field [0001] This invention relates to the sealing compound for liquid crystal display elements which can suppress insertion of a liquid crystal into a sealing compound and contamination of a liquid crystal by a sealing compound. Moreover, this invention relates to the vertical conduction material and liquid crystal display element produced 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 viewpoint of shortening the tact time and optimizing the amount of liquid crystal usage, the method disclosed in Patent Document 1 and Patent Document 2, which contains A liquid crystal dropping method called the dropping process, which uses a photothermal combination of a curable resin, a photopolymerization initiator, and a thermosetting agent to use a curable sealant. [0003] In the dropping process, first, ...
