Liquid crystal display element and sealing compound for liquid crystal display elements

Abstract

An object of the present invention is to provide a liquid crystal display element capable of suppressing seal breakage, liquid crystal contamination, and gap defects due to springback. Moreover, the object of this invention is to provide the sealing compound for liquid crystal display elements which can be used for manufacture of this liquid crystal display element. The present invention is a liquid crystal display element having a structure in which liquid crystal is encapsulated in a unit formed by sealing the periphery of two substrates with a linear sealing portion containing particles, wherein the sealing portion When the sealing width is set to 100%, the average particle size of the particles contained in the area from the centerline of the above-mentioned sealing part to the positions of 10% in the direction of both ends is larger than that from the two ends of the above-mentioned sealing part to the center line. Each direction is the average particle diameter of the particles contained in the area up to the 10% position.

Description

technical field [0001] The present invention relates to a liquid crystal display element capable of suppressing seal breakage, liquid crystal contamination, and suppressing gap defects due to rebound. Moreover, this invention relates to the sealing compound for liquid crystal display elements which can be used for manufacture of this liquid crystal display element. Background technique [0002] In recent years, with respect to the manufacture method of liquid crystal display element such as liquid crystal display unit, from shortening production tact time (tact time), the point of view of optimizing liquid crystal consumption, mainstream has changed from the vacuum injection method in the past to for example like patent document 1, As disclosed in Patent Document 2, a liquid crystal dropping method called a dropping method uses a photothermal combined curing type sealant containing a photocurable resin, a photopolymerization initiator, a thermosetting resin, and a thermosett...

AI Technical Summary

Problems solved by technology

[0005] However, if a liquid crystal display element with a narrow edge design is manufactured by the dropping process, there is a problem that there are parts in the sealing part that cannot be irradiated with light due to the black matrix, so photocurable resin that is not sufficiently illuminated and cured is produced In the part where the uncured sealant is in contact with the liquid crystal, the liquid crystal penetrates into the sealant, and the seal is damaged and the liquid crystal leaks, or the liquid crystal is polluted by the sealant being dissolved into the liquid crystal.
