Description
Technical field
The present invention relates to the sealing material for liquid crystal display device for the anti-penetrability that can take into account cementability and solidfied material.Separately
Outside, the present invention relates to the conductive materials up and down and liquid crystal display element that use the sealing material for liquid crystal display device and manufacture.
Background technology
In recent years, the manufacturing method as liquid crystal display elements such as liquid crystal displays, from shortening productive temp time, liquid
From the perspective of the optimization of brilliant dosage, used as patent document 1, it is disclosed Patent Document 2, used and contained
The liquid crystal of curable resin, the photo-thermal of Photoepolymerizationinitiater initiater and thermal curing agents and the technique that is referred to as dripping with curing type sealant
It drips mode.
In technique of dripping, first, formed on one in two electroded substrates by distributor rectangular
Seal pattern.Next, drip to the fine droplet of liquid crystal in the sealing frame of substrate in the state that sealant is uncured,
It is overlapped another substrate under vacuum, the light such as ultraviolet light are irradiated to sealing to carry out precuring.Thereafter it heats to carry out main solidification,
Make liquid crystal display element.The technique of dripping becomes the mainstream of the manufacturing method of liquid crystal display element now.
In addition, the present age universal in mobile phone, portable game machine etc., the various mobile devices with liquid crystal display panel,
The miniaturization of device is the project needed most.As the method for miniaturization, the narrow architrave of liquid crystal display part can be enumerated, such as will
The position of sealing is configured under black matrix" (hereinafter also referred to narrow architrave design).
It is designed along with this narrow architrave, in liquid crystal display element, becomes close from pixel region to the distance of sealant, hold
It is also easy to produce and shows unevenness caused by sealant pollutes liquid crystal.
In addition, along with tablet computer terminal, mobile terminal it is universal, liquid crystal display element is more required in high temperature height
The moisture-proof reliability of driving etc. under wet environment, prevents sealant further requirement the performance of the immersion from external water.For
The moisture-proof reliability for improving liquid crystal display element, needs the immersion for carrying out the water at the interface of self-sealing substance and substrate etc. in order to prevent
And cementability of the sealant to substrate etc. is improved, and improve the anti-penetrability of sealant.As the anti-moisture-inhibiting for improving sealant
The method of property, it may be considered that the method for filler such as coordinating talcum.However, coordinate the fillers such as talcum even if as described above,
But in the case where carrying out stringent moisture-proof reliability test, still has liquid crystal display element and the problems such as display is uneven occurs.
