Problems solved by technology

[0013] However, when liquid crystal display elements are produced by the dropping process, many ultraviolet rays irradiated to cure the sealant also irradiate the liquid crystal, so if the sealant is cured with short-wavelength and high-energy ultraviolet rays, the liquid crystal will also deteriorate at the same time. , so that the display quality of the liquid crystal display element is significantly reduced, and the reliability is reduced

Abstract

It is an object of the present invention to provide a sealant for a One prop Fill process which hardly causes a peeling phenomenon between the sealant and a substrate in production of liquid crystal display device since the sealant has excellent adhesion to the substrate, and which is most suitable for producing a liquid crystal display device having low color irregularity in liquid crystal display since the sealant does not cause liquid crystal contamination, and relates to a sealant for a One prop Fill process, in which in production of liquid crystal display device by a One prop Fill process, even a portion where light may be not directly irradiated can be adequately cured, a liquid crystal is not deteriorated by ultraviolet light to be irradiated in curing the sealant, and high display quality and high reliability of the liquid crystal display device can be realized, a vertically conducting material, and a liquid crystal display device obtained by using these. The present invention is directed to a sealant for a One prop Fill process, which contains a (meth)acrylate compound having a structure represented by the following general formula (1), 10 to 70% by weight of a curable resin component contained in the sealant being the (meth)acrylate compound. In the general formula (1), R1 represents a hydrogen atom or a methyl group, X represents one species selected from the group expressed by the following chemical formula (2), Y represents one species selected from the group expressed by the following chemical formula (3), A represents a ring opening structure of cyclic lactone, and n has a value of zero or one.

Description

technical field [0001] The present invention relates to a liquid crystal display which is most suitable for a liquid crystal display with less color unevenness due to excellent adhesion to a substrate in the manufacture of a liquid crystal display element, which hardly causes peeling with the substrate, and which does not cause liquid crystal contamination. Sealant for the liquid crystal dropping process in the manufacture of components, and even if there is a position that is not directly irradiated with light when the liquid crystal display element is manufactured by the dropping process, it can be fully cured and the ultraviolet rays irradiated during curing will not Sealant for liquid crystal dropping process, vertical conduction material, and liquid crystal display element using them that cause liquid crystal to deteriorate and realize high display quality and high reliability of liquid crystal display element. Background technique [0002] Conventionally, a liquid crys...
