Description

The present invention relates to an image display device, a method for manufacturing the same, and an electric / electronic device equipped with the image display device.

In image display parts such as mobile phones, smartphones, touch panels, etc., there is a conventional air gap between the liquid crystal module, organic EL module or organic TFT module and the uppermost transparent cover board (PET film, tempered glass, acrylic plate, etc.). Thus, even when the cover is broken by an impact from the outside, the module is not affected (air gap structure).
In recent years, optically curable with light (UV) using urethane acrylate and epoxy acrylate with photopolymerizable functional groups as binder polymers for the purpose of improving visibility and impact resistance of some flat panel displays. Elastic resin curable compositions are beginning to be used.

In addition to the above-mentioned conventional electrical devices aimed at improving the visibility and impact resistance, the demand for car navigation systems, new multi-tablet machines, electronic paper, and multi-touch PC displays is increasing. The screen size of these electronic devices is also increasing.

Due to the increase in screen size, the following problems have been pointed out in the method for bonding image display device members used in image display devices of the size of mobile phones and smartphones.
<Problems associated with display and screen size increase>

(1) Usually, when a transparent cover board, a touch sensor, and a display module, which are members for an image display device, are bonded together, an adhesive tape for engineering (OCA tape: Optical Clear Adhesive Tape) is provided between the transparent cover board and the touch sensor. Alternatively, it is filled with a UV curable resin, and at the same time, it is required to fill a resin layer between the touch sensor and the liquid crystal module in order to improve visibility. Here, since there is a portion through which UV does not transmit between the touch panel / liquid crystal module, a UV curable resin cannot be used, and therefore an OCA tape is used. However, the OCA tape has a problem that it is difficult to repair and the defective rate is increased when bubbles or misalignment occurs at the time of bonding. For this reason, it is desirable to use a UV curable resin that can be repaired by peeling off the adhesive layer during temporary fixing after bonding, in order to bond image display device members (particularly touch sensors and liquid crystal modules). It was rare.

(2) Due to the increase in screen size, the area where UV light that is a trigger for curing by the design of the outermost surface cover does not pass (for example, black printing, etc.) increases, resulting in an unreacted part. To do.

(3) When a liquid adhesive is applied to a member for an image display device such as a transparent cover board, a display module, or a touch sensor, the tact time (time required for the process) becomes longer with a linear application pattern using a conventional dispenser. .

(4) As the screen size increases, the weight of the image display device member also increases. Therefore, the adhesive protrudes from the end of the image display device member during bonding, and as a result, the surrounding circuits are contaminated. .

As a candidate technology that may improve the curability of the UV non-transmitting part, a cured product using an organic polymer having a functional group at the end of the main chain having flexibility (impact resistance), particularly living polymerization is used. There is an example of a cured product using a polymer synthesized by use, but there is a problem in terms of fast curability and adhesiveness, and the use of the present invention is not intended (Patent Documents 1 and 2). ).

These amine compounds may be used alone or in combination of two or more.

When the acid / base catalyst is added, it may be mixed and reacted with the curing catalyst in advance, or may be mixed later. If they are mixed and reacted in advance, the catalytic activity becomes higher and fast curability may be realized.
In addition, the equivalent ratio (molar ratio) of acid to amine is 0.1 to 50 in terms of acid / amine. 0.3-40 are preferable and 0.5-30 are more preferable at the point of sclerosis | hardenability, pot life, and storage stability.

On the other hand, if the amount of the curing catalyst exceeds 50 parts by weight, the pot life may become too short, which is not preferable from the viewpoint of workability.

Furthermore, a silicon compound having no amino group or silanol group may be added as a promoter. These silicon compounds are not limited, but phenyltrimethoxysilane, phenylmethyldimethoxysilane, phenyldimethylmethoxysilane, diphenyldimethoxysilane, diphenyldiethoxysilane, triphenylmethoxysilane and the like are preferable.

The compounding amount of the silicon compound is preferably about 0.01 to 20 parts, more preferably 0.1 to 10 parts with respect to 100 parts of the compound (b) having at least one hydrolyzable silyl group on average. When the compounding amount of the silicon compound is below this range, the effect of accelerating the curing reaction may be reduced. On the other hand, when the compounding amount of the silicon compound exceeds this range, the hardness and tensile strength of the cured product may decrease.

In addition, it is possible to control the sclerosis | hardenability, mechanical physical property, etc. of the said curable composition (A / B) according to the objective and use by the kind and addition amount of a curing catalyst (curing agent).
Moreover, it is possible to change the kind and addition amount of a curing catalyst (curing agent) depending on the reactivity of the silyl group of the polymer having a crosslinkable silyl group, and if the reactivity is high, 0.01 to 1 part It can be cured sufficiently in a small amount.

When Y is an alkoxy group, the smaller the number of carbons, the higher the reactivity, and the larger a the higher the reactivity, so that it can be sufficiently cured in a small amount.

<< Compounding agent >>
Various kinds of compounding agents may be further added to the curable composition (A / B) depending on the intended physical properties.

<Polymerizable monomer and / or oligomer (e)>
A monomer and / or oligomer (e) can be added to the curable composition (A / B) as long as the effects of the present invention are not impaired. In this case, a monomer and / or oligomer having a radical polymerizable group or a monomer and / or oligomer having an anion polymerizable group is preferable from the viewpoint of curability.

Examples of the radical polymerizable group include (meth) acryloyl group such as (meth) acryl group, styrene group, acrylonitrile group, vinyl ester group, N-vinylpyrrolidone group, acrylamide group, conjugated diene group, vinyl ketone group. And vinyl chloride group.
Among these, those having a (meth) acryloyl group similar to the vinyl polymer that can be used in the present invention are preferable.
Examples of the anionic polymerizable group include (meth) acryloyl group such as (meth) acryl group, styrene group, acrylonitrile group, N-vinylpyrrolidone group, acrylamide group, conjugated diene group, vinyl ketone group and the like. . Among these, those having a (meth) acryloyl group similar to the vinyl polymer that can be used in the present invention are preferable.

Examples of the oligomer include those described in paragraph [0132] of JP-A-2006-265488.

Of the above, monomers and / or oligomers having a (meth) acryloyl group are preferred. The number average molecular weight of the monomer and / or oligomer having a (meth) acryloyl group is preferably 5000 or less. Furthermore, in the case of using a monomer for improving the surface curability and reducing the viscosity for improving workability, it is more preferable that the molecular weight is 1000 or less because of good compatibility.

In particular, when it is desired to obtain a cured product having high strength with these fillers, mainly crystalline silica, fused silica, anhydrous silicic acid, hydrous silicic acid, carbon black, surface-treated fine calcium carbonate, calcined clay, clay and activity A filler selected from zinc oxide and the like is preferable.
Among them, the specific surface area (according to BET adsorption method) of ^{50 m} 2 / g or more, usually 50 to 400 m ² / g, is preferably 100 to 300 m ² / g approximately ultrafine powdery silica preferred. Further, silica whose surface has been previously hydrophobically treated with an organosilicon compound such as organosilane, organosilazane, diorganopolysiloxane, etc. is more preferred.

In addition, when it is desired to obtain a cured product (cured resin layer) having low strength and large elongation, a filler mainly selected from titanium oxide, calcium carbonate, talc, ferric oxide, zinc oxide, shirasu balloon, etc. Is preferred.
In general, when calcium carbonate has a small specific surface area, the effect of improving the breaking strength and breaking elongation of a cured product (cured resin layer) may not be sufficient. The greater the specific surface area value, the greater the effect of improving the breaking strength and breaking elongation of the cured product (cured resin layer).

Furthermore, it is more preferable that the calcium carbonate is subjected to a surface treatment using a surface treatment agent. When surface-treated calcium carbonate is used, the workability of the curable composition (A / B) is improved as compared with the case of using non-surface-treated calcium carbonate, and the storage stability of the curable composition is improved. It is considered that the effect is further improved.

A well-known thing can be used as said surface treating agent, For example, the surface treating agent of Unexamined-Japanese-Patent No. 2005-232419 Paragraph [0161] is mentioned. The treatment amount of the surface treatment agent is preferably in the range of 0.1 to 20% by weight and more preferably in the range of 1 to 5% by weight with respect to calcium carbonate. When the treatment amount is less than 0.1% by weight, the workability improving effect may not be sufficient, and when it exceeds 20% by weight, the storage stability of the curable composition may be lowered.
Although there is no particular limitation, when calcium carbonate is used, if the effect of improving the thixotropy of the curable composition, the breaking strength of the cured product (cured resin layer), the elongation at break, etc. is particularly expected, the calcium carbonate carbonate Is preferably used. On the other hand, the heavy calcium carbonate described in paragraph [0163] of JP-A-2005-232419, which may be added for the purpose of increasing the amount of the compound, reducing costs, or the like, can also be used.

When the filler is used, the addition amount is preferably 5 to 1000 parts by weight, preferably 20 to 500 parts by weight with respect to 100 parts by weight of the total of component (a) and component (b). More preferably, it is used in a range of 40 to 300 parts by weight. If the blending amount is less than 5 parts by weight, the effect of improving the breaking strength, breaking elongation, adhesion and weather resistance of the cured product (cured resin layer) may not be sufficient. The workability of the composition may be reduced.

<Micro hollow particles>
To the curable composition (A / B), fine hollow particles are added in combination with the reinforcing filler described above for the purpose of reducing the weight and cost without causing a significant decrease in physical properties. be able to. Such fine hollow particles (hereinafter sometimes referred to as “balloons”) are not particularly limited, but for example, as described in “Latest Technology for Functional Fillers” (CMC), Examples thereof include hollow bodies (inorganic balloons and organic balloons) made of inorganic or organic materials having a diameter of 1 mm or less, preferably 500 μm or less, and more preferably 200 μm or less.
In particular, it is preferable to use a micro hollow body having a true specific gravity of 1.0 g / cm ³ or less, and more preferably to use a micro hollow body having a specific gravity of 0.5 g / cm ³ or less.

Examples of the inorganic balloon and the organic balloon include balloons described in paragraphs [0168] to [0170] of JP-A-2005-232419. The balloons may be used alone or in combination of two or more. Furthermore, the surface of these balloons is made of fatty acid, fatty acid ester, rosin, rosin acid lignin, silane coupling agent, titanium coupling agent, aluminum coupling agent, polypropylene glycol, etc. to improve dispersibility and workability of the compound. Those processed in the above can also be used. These balloons are used for weight reduction and cost reduction without impairing flexibility and elongation / strength among physical properties when the compound is cured.

The addition amount of the balloon is not particularly limited, but is preferably 0.1 to 50 parts by weight, more preferably 0.1 to 30 parts by weight with respect to 100 parts by weight of the total of component (a) and component (b). Can be used in a range. If the amount is less than 0.1 parts by weight, the effect of reducing the weight is small. If the amount is more than 50 parts by weight, a decrease in tensile strength may be observed among the mechanical properties when the curable composition is cured. Moreover, when the specific gravity of a balloon is 0.1 or more, the addition amount is preferably 3 to 50 parts by weight, more preferably 5 to 30 parts by weight.

Among these, polyester plasticizers and vinyl polymers are preferable because the effect of reducing the viscosity is remarkable and the volatilization rate during the heat resistance test is low. Moreover, the polymer plasticizer which is a polymer having a number average molecular weight of 500 to 15000 is added, such as the viscosity of the curable composition and the tensile strength and elongation of the cured product obtained by curing the curable composition. Compared with the case where a low molecular plasticizer which is a plasticizer which does not contain a polymer component in the molecule can be adjusted, the initial physical properties can be maintained over a long period of time. Although not limited, the polymer plasticizer may or may not have a functional group.

Although the number average molecular weight of the said polymeric plasticizer was described as 500-15000, Preferably it is 800-10000, More preferably, it is 1000-8000. If the molecular weight is too low, the plasticizer may flow out over time when exposed to heat or in contact with a liquid, and the initial physical properties may not be maintained over a long period of time. Moreover, when molecular weight is too high, a viscosity will become high and there exists a tendency for workability | operativity to fall.

Of these polymer plasticizers, those compatible with the vinyl polymer are preferred. Of these, vinyl polymers are preferred from the viewpoints of compatibility, weather resistance, and heat aging resistance. Among the vinyl polymers, (meth) acrylic polymers are preferable, and acrylic polymers are more preferable.

Examples of the acrylic polymer include those obtained by conventional solution polymerization and solvent-free acrylic polymers.
The latter acrylic plasticizer does not use a solvent or a chain transfer agent, and is a high-temperature continuous polymerization method (USP 4414370, JP 59-6207, JP-B-5-58005, JP 1-331522, USP 5010166). It is more preferable for the purpose of the present invention. Examples thereof include, but are not particularly limited to, for example, Toagosei UP series and the like (see the Industrial Materials October 1999 issue). Of course, the living radical polymerization method can also be mentioned as another synthesis method. According to this method, the molecular weight distribution of the polymer is narrow and the viscosity can be lowered, and the atom transfer radical polymerization method is more preferable, but it is not limited thereto.

The molecular weight distribution of the polymer plasticizer is not particularly limited, but is preferably narrow and preferably less than 1.8. 1.7 or less is more preferable, 1.6 or less is still more preferable, 1.5 or less is more preferable, 1.4 or less is especially preferable, and 1.3 or less is the most preferable.

The plasticizer containing the above-mentioned polymer plasticizer may be used alone or in combination of two or more, but is not necessarily required. Further, if necessary, a high molecular plasticizer may be used, and a low molecular plasticizer may be further used in a range that does not adversely affect the physical properties.
In addition, these plasticizers can also be mix | blended at the time of manufacture of (a) component or (b) component which consists of organic polymers.

Although the usage-amount in the case of using a plasticizer is not limited, Preferably it is 1-100 weight part with respect to 100 weight part of (a) component and (b) component total, More preferably, it is 5-50 weight part. If the amount is less than 1 part by weight, the effect as a plasticizer tends to be hardly exhibited, and if it exceeds 100 parts by weight, the mechanical strength of the cured product (cured resin layer) tends to be insufficient.

<Reactive diluent>
For the curable composition (A / B), in addition to the plasticizer, a reactive diluent described below may be used. If a low-boiling compound that can be volatilized during curing is used as a reactive diluent, it will change shape before and after curing, or it may adversely affect the environment due to volatiles. An organic compound having a boiling point of 100 ° C. or higher is particularly preferable.

Specific examples of the reactive diluent include, for example, 1-octene, 4-vinylcyclohexene, allyl acetate, 1,1-diacetoxy-2-propene, methyl 1-undecenoate, 8-acetoxy-1,6-octadiene. However, it is not limited to these.
The amount of the reactive diluent added is preferably 0.1 to 100 parts by weight, more preferably 0.5 to 70 parts by weight, and still more preferably 100 parts by weight of the total of component (a) and component (b). 1 to 50 parts by weight.

<Light stabilizer>

Various types of light stabilizers are known, and are described in, for example, “Antioxidant Handbook” issued by Taiseisha, “Degradation and Stabilization of Polymer Materials” (235-242) issued by CM Chemical Co., Ltd. Although various things are mentioned, it is not necessarily limited to these.
Although not particularly limited, among the light stabilizers, an ultraviolet absorber is preferable.

Further, hindered amine compounds are also preferable, and specific examples of such compounds include those described in JP-A-2006-274084, but are not limited thereto. Furthermore, since the combination of the ultraviolet absorber and the hindered amine compound may exhibit more effect, it is not particularly limited, but may be used in combination, and it is preferable to use in combination.

The light stabilizer may be used in combination with the above-described antioxidant, and it is particularly preferable because the effect is further exhibited by using it together and the weather resistance may be improved. Tinuvin C353, Tinuvin B75 (all of which are manufactured by Ciba Geigy Japan, Inc.) in which a light stabilizer and an antioxidant are mixed in advance may be used.

It is preferable that the usage-amount of a light stabilizer is the range of 0.1-10 weight part with respect to 100 weight part of (a) component and (b) component total. If the amount is less than 0.1 parts by weight, the effect of improving the weather resistance is small.
