In recent years, the application extension of liquid crystal display is to the large display screen curtain of televisor etc., and the demand to liquid crystal display in a lot of purposes becomes big.Therefore, about the manufacturing of liquid crystal panel,, require substrate maximization and production time per piece (time of each operation) to shorten in order further to improve production.
When making liquid crystal indicator, after being coated on liquid crystal sealing agent on the glass substrate by methods such as a glue coating or silk screen printings, seal and form the unit, in vacuum, liquid crystal is injected in the unit from the liquid crystal injecting port that is arranged on the unit part, use sealing agent or sealing compound to seal this liquid crystal injecting port, make thus (vacuum impregnation).
In addition, in the cofferdam that is formed from a resin (weir), fit behind the dispenser method and the liquid crystal drip-injection method (method under the liquid crystal drop) that makes resin solidification also just in practicability.In liquid crystal drip-injection method, at first, form the rectangular seal pattern that constitutes by uncured sealing agent by some glue (デ イ ス ペ Application ス) on the plate base in 2 belt electrode transparency carriers.Then, on under the uncured state of sealing agent, the fine droplet of liquid crystal being instiled and being coated in the frame of seal pattern of transparency carrier comprehensively, fit with another transparency carrier immediately then, make liquid crystal cells, to seal pattern part irradiation ultraviolet radiation, carry out Procuring (Provisional sclerosis).Thereafter, curing (this sclerosis) is led in heating as required, makes liquid crystal display.Under reduced pressure carry out if make the operation of liquid crystal cells by adhesive substrates, just can be with high efficiency system liquid making crystal display element, at present, this drip-injection method is the main manufacture method of liquid crystal display device.
When making liquid crystal display device by liquid crystal drip-injection method, the seal pattern of the liquid crystal display device that generation makes deforms, liquid crystal embeds phenomenon (the embedding (Cha Write body) phenomenon in the seal pattern), and have the problem of the orientation of upsetting near the liquid crystal the sealing pattern.As the method that addresses this problem, think the method for using the common high sealing agent of viscosity ratio to form seal pattern is for example arranged, but may make a colloidality (デ イ ス ペ Application ス) variation, the style of calligraphy characterized by hollow strokes (か The れ) when producing some glue, broken string problems such as (Line cut れ).In addition, be purpose with in recent years further shortening production time per piece etc., in order to improve a glue speed and can easily to utilize silk screen printing to form seal pattern, require viscosity lower and do not embed the sealing agent of phenomenon.
About this problem, in patent documentation 1, reported before the operation of making liquid crystal cells, by uncured seal pattern thickening (tackify) is prevented to embed phenomenon.But, be low viscosity below the 100Pas and viscosity can not rise terrifically in the preliminary drying operation and after the preliminary drying operation the liquid crystal sealing agent that is used for liquid crystal drip-injection method about the initial viscosity after the firm preparation, also beyond example.
In addition, in patent documentation 2 and 3, reported the liquid crystal sealing agent that comprises the rubbery polymer particulate.In two documents, below all non-100Pas of initial viscosity.In patent documentation 4, reported the liquid crystal sealing agent of the cross-linked rubber that comprises core shell structure and specific maleimide compound, but initial viscosity surpasses 100Pas.In patent documentation 5, reported the liquid crystal sealing agent of the cross-linked rubber that comprises core shell structure, but initial viscosity surpasses 100Pas.And then, the rubbery polymer particulate be difficult for the shading light part that shone by UV when being used for being suppressed at photocuring the sealing agent composition when thermofixation stripping to the composition of liquid crystal, the effect of the thickening composition when not reporting it as preliminary drying.

Industrial applicability
As mentioned above, liquid crystal sealing agent of the present invention except satisfy can tackle serigraphy liquid crystal drip-injection method with the desired initial viscosity of liquid crystal sealing agent, the thixotropy, the production method of liquid crystal pollution, serigraphy, cell gap, the liquid crystal characteristics such as embedding in sealant are also excellent. On the other hand as can be known, although the comparative example initial viscosity is low, excess stickiness increases and generation unit gap not during precuring, perhaps not thickening and liquid crystal pollution, some colloidality variation after the precuring. In addition we know, in the high comparative example of initial viscosity, some colloidality or serigraphy are poor. Therefore can say that by operation, the liquid crystal sealing agent of the present application contaminative to liquid crystal in whole operation is low, embeddability, operability during to the coating operability of substrate, liquid crystal drip-injection method are excellent, reliability is high.
