Technical field
The present invention relates to the pollution to liquid crystal low, to highly sensitive, the polymerizable monomer that sensitization effect is also excellent of the light of long wavelength and macromolecular compound that the polymerization of this polymerizable monomer is obtained. In addition, the present invention relates to containing this polymerizable monomer and/or the Photocurable resin composition of this macromolecular compound, the sealing material for liquid crystal display device using this Photocurable resin composition and make and the conductive material up and down using this sealing material for liquid crystal display device and manufacturing and liquid crystal display device.
Background technology
In recent years, as the manufacture method of the liquid crystal display device such as liquid crystal display, from shortening the beat time, use the viewpoint such as optimization of amount of liquid crystal to consider, it may also be useful to be as disclosed in patent documentation 1, patent documentation 2, employ the photo-thermal containing curable resin, Photoepolymerizationinitiater initiater and thermal curing agents and with the sealing agent of curing, the liquid crystal drop under type that is called as technique of dripping.
Dripping in technique, first, at 2 with a slice of the transparency carrier of electrode is formed rectangular seal pattern by divider. Then, the tiny droplets of liquid crystal dripping to when sealing agent does not solidify whole in the frame of transparency carrier, another transparency carrier overlapping, carries out temporary fixing to light such as sealing portion irradiation ultraviolet radiations immediately. Thereafter, carry out when liquid crystal is annealed heating and carrying out main solidification, make liquid crystal display device. If under reduced pressure carrying out the laminating of substrate, then can manufacturing liquid crystal display device with extreme efficiency, at present, this technique of dripping becomes the main flow of the manufacture method of liquid crystal display device.
In addition, universal present at the various mobile equipment with liquid crystal panel such as portable phone, portable game, the miniaturization of device is the problem wishing most to realize. As the method for the miniaturization of device, the narrow frame of liquid crystal display part can be enumerated, such as, under the position in sealing portion being configured in black matrix" (designing hereinafter also referred to narrow frame).
But, in narrow frame designs, sealing agent is configured in the underface of black matrix", if therefore carrying out dripping technique, then the light of the irradiation when making sealing agent carry out photocuring is covered, and there is the inside that light does not arrive sealing agent, and solidification becomes insufficient problem. If the solidification of sealing agent becomes insufficient like this, then there is the problem easily producing liquid crystal pollution in the sealing agent composition stripping to liquid crystal do not solidified.
In patent documentation 3, disclose and the Photoepolymerizationinitiater initiater of highly sensitive is engaged in sealing agent.But, if only coordinating the Photoepolymerizationinitiater initiater of highly sensitive, then cannot make the abundant photocuring of sealing agent. In addition, in patent documentation 4, disclose and the Photoepolymerizationinitiater initiater of highly sensitive and sensitizing agent combination are engaged in sealing agent. But, owing to using sensitizing agent, therefore there is the problem easily producing liquid crystal pollution.
