The liquid crystal display device has a liquid crystal panel including a liquid crystal display unit and an optical film attached to a polarizing plate on both outer surfaces of the liquid=display unit, and the crystal display unit is formed by previously forming a transparent electrode and a pixel pattern on the surface. A pair of glass substrates having a thickness of about 1 mm or so are filled with a liquid crystal with a gap of about several μm, and then sealed to produce a liquid crystal panel. An image display device typified by a liquid crystal image display device having such a configuration is a thin display member that is easily damaged. Therefore, in particular, in applications such as mobile phones, game machines, digital cameras, and car parts, a transparent front panel (protective panel) is usually provided in a space between the front surface of the image display device. Further, in the conventional large-sized liquid crystal image display device, a polarizing plate is provided on the front surface of the liquid crystal panel. The surface of the polarizing plate is subjected to an anti-glare (AG) treatment to improve visibility by reducing reflection of light in front of the image display device. In the case of a large-sized image display device, in general, in order to improve the shock absorption of the device, a front panel or the like is not separately provided, and the whole liquid crystal panel and the entire device 4 201231602 jpif are financially impactful. . The problem of such a large-sized liquid crystal image display device is that the image appears blurred due to the AG processing; if the surface of the image display device is touched, the liquid crystal panel is curved and the image is disordered; the dirt on the surface is difficult to fall due to the AG processing. On the other hand, if it is strongly wiped, damage is likely to occur. In addition, it is considered that the impact resistance of the liquid crystal panel itself is lowered with the increase in the size of the liquid crystal panel in the future, and the impact resistance of the image display device is problematic. In view of the above situation, it is conceivable to provide a front panel to which an anti-reflection (AR) process is applied to the front surface of the liquid crystal panel, thereby eliminating the disadvantage of the source-AG processing. However, when there is air between the current panel and the liquid crystal panel, it can be considered that the (four) is caused by the scattering of the light, thereby causing a decrease in the transmittance and caused by the ghost image (gh〇st). The decline in image quality, etc. Therefore, there has been proposed a technique of filling a space between a front panel and a liquid crystal panel such as a fine resin (see, Patent Document 1, Patent Document 2, Patent Document 3, and Patent Document 4). Further, in recent years, touch panels have been set up in mobile phones, game machines, digital cameras, car parts, notebook-turning computers, desktop personal computers, personal computers, and blood-visual S. In the liquid crystal image display device, the second layer of the liquid crystal image display device is formed into a front panel (protective panel), a touch panel, and a liquid crystal panel in a stacking structure. The front panel (the health panel) and the touch panel and the touch panel are formed. There is a certain space between the liquid crystal panel and the liquid crystal panel. _Because of the scattering of 1 from 71, the image is reduced due to the re-image... λ! ί degree or redundancy, and the transmittance is lowered. In order to solve the problem, 201231602 ~r\J^U 々if is also important to fill in the above space. However, when the image display device (display) is applied to a television set, the image display device falls under the Lee Ball (four) impact test according to the Underwrite Laboratcmes (UL) specification or the radio wave banning method f. There must be no scattering of components, or steel, through the components. At present, in a glass cathode ray tube (CRT) widely used, in order to satisfy the above specifications, it is necessary to design a glass plate to be thick, and there is a tendency to increase the mass of the entire CRT. For this reason, a technique of providing a synthetic resin protective film having a self-healing property on a surface area of a glass plate has been proposed as a method of providing a film-protecting film to a surface of a glass plate without reducing the thickness of the glass plate (see Patent Document No. and Patent Document 6). ). In addition, in the plasma display panel (PDP) which has been attracting attention as an example of a flat panel display (FPD) in recent years, 'in order to prevent damage of the panel portion' is interposed in front of the pDp (visible side). A front panel such as glass having a thickness of about 3 mm is provided in a space of about 1 mm to 5 mm. However, as the size of the PDP increases, the area of the front panel also increases. Therefore, the mass of the entire pDp tends to become heavier. Therefore, in order to prevent the image display device (display) from being damaged, a technique of laminating a specific resin on the surface of the display or stacking a filter having a specific resin on the surface of the display has been proposed (see Patent Document 7, Patent Document 8, Special offer 9 and patent documents 1〇).

Various techniques of the purpose, but when these techniques are applied to a large-sized liquid crystal image display device, satisfactory results cannot be obtained, and further development is desired. In particular, in recent years, rabbits are studying the use of plastic sheets for the front panel from the viewpoint of quality reduction, cost reduction, and good processability. However, when using a plastic front panel, it is easier than a glass front panel. Warpage caused by changes in temperature or humidity occurs, and thus defects such as peeling or bubbles are likely to occur. In particular, when the adhesion between the current panel and the image display panel is low, it is likely to cause a problem of occurrence, and a high adhesion force is required between the resin composition for bringing the front panel into close contact with the image display panel. However, in the technique disclosed in the above patent document, the adhesion of the plastic front panel to the resin composition or the reliability of the image display device with the plastic front panel is not necessarily the same. In view of the above, a first object of the present invention is to provide an optical adhesive resin composition suitable for use in an image display device, and an optical adhesive material using the same, which is an optical adhesive material. The resin composition is excellent in transparency, and has sufficient adhesion to a plastic front panel, a touch panel, an image display panel (a liquid crystal panel, a PDP panel, an organic electroluminescence (EL) panel, etc.), and has a protective image display device. The required impact absorption and the flexibility and handleability required to produce an image display device with a plastic front panel. Further, a second object of the present invention is to provide an optical adhesive resin composition suitable for use in an image display device excellent in high-temperature reliability or moisture-resistant reliability, and an optical adhesive sheet for use. In order to solve the above problems, the present inventors have found that the above problems can be solved by using a (fluorenyl) acrylate polymer having a mercapto group. The present invention is an invention completed based on the above findings.

The optical adhesive resin composition of the present invention and the optical adhesive sheet which is a one-piece cured product have high adhesion to the plastic front panel, and are excellent in transparency or impact absorption, so that the image display device can be recorded. And the use of filter screens for image display devices. For example, when the optical adhesive resin and the adhesive sheet of the present invention are used as a transparent resin layer of an image display device, excellent high-temperature reliability, wet reliability, and impact absorption can be achieved in image display loading. Sex. [Embodiment] The optical adhesive resin composition of the present invention comprises a (fluorene) (fluorenyl) acrylate polymer and a (fluorene) (meth) acrylate monomer, characterized in that the (fluorenyl) acrylate The ester polymer has a guanamine group. In the optical adhesive resin composition of the present invention, as described above, a polymer having a specific structure (Α) is used in combination with a component which is a diluent monomer, whereby compatibility can be improved, in particular The solubility of the polymer component can be improved by setting the monomer constituting the (Α) polymer to the same component as the (Β) diluted monomer. Therefore, even when a high molecular weight polymer is used, a resin composition excellent in transparency and a cured product can be obtained. Further, by preparing and using a resin composition containing a polymer having a high molecular weight at a relatively high concentration, even if the film thickness is thin, it is possible to realize a member excellent in impact absorption 201231602. Further, in the optical adhesive resin composition of the present invention, the monomer component of the rituximab is diluted with the polymer component, whereby the resin composition can be molded without diluting with a solvent, and it is easy to produce a gas and a package. And a film or sheet having a thickness. In the following, the components (A) to (D) constituting the optical adhesive resin composition of the present invention will be described in detail.

When the temperature is 1G] and the half-life temperature is aerodynamic, the storage stability of the resin composition is good. On the other hand, if the half-life temperature is 8 (rc or less, it is not required to be high during the hardening reaction: It does not cause deterioration of the characteristics of the liquid crystal or the polarizing plate. The problem of deterioration of display characteristics of the liquid crystal display is caused by the problem of the deterioration of the display characteristics of the liquid crystal display. When the thermal polymerization initiator having a relatively high temperature in the semi-agricultural period is used, it is easy to ensure the tree. Stability is stable, but the reactivity is lowered. Therefore, it is necessary to set the amount of the starting agent to be relatively large. Conversely, at 10 hours 27 201231602, the half-life temperature is low, and the thermal polymerization of the resin composition is low.

These hardening methods can also be used in combination. The optical adhesive sheet of the present invention may be used by being bonded to glass, another substrate or the like. 28 201231602 The optical adhesive resin composition of the month does not intrude on the transparency of the material used in the liquid crystal image L·丁t\s-PDP, organic display, etc., so it can be preferably used. A variety of images are displayed for 4 readings. Therefore, the adhesive sheet described in the preferred embodiment of the present invention is used as an impact absorbing layer or a transparent filling layer for filtering the image display device and the image display device. (4) When the adhesive sheet is used as the impact absorbing layer of the image display device, the glass transition temperature of the cured product of the object is preferably 屹 or less. The glass transition temperature of the right hardened material is below = = ensured that it will not crack due to impact. On the above = _gm2 〇 C ~ 6 〇 C. Further, when the adhesive sheet is applied to an image; when the page is not placed, the light is 80% or more, more preferably 9% or more, with respect to the visible light region (wavelength · Griffon ~ 780 nm). Furthermore, it is possible to make a self-standing sheet or film by using an optical secret tree, and use the sheets or the prior art adhesive sheets. For such optical use, methods such as die-casting can be used. Further, the hardening reaction of the light 2 = $ can be carried out by heating or irradiating light such as ultraviolet rays, electron beams, or the like. When the optical film of the present invention is formed into a self-supporting sheet or film, its film thickness is 0.01 mm to 3 mm. When the film thickness is 0.01 mm or more, the panel or the front panel can be undulated without generating bubbles. ‘, below, good optical properties are obtained. In this respect, it is more preferably 0.05 mm to 3 mm. 29 201231602 ί ί 为 为 为 为 为 为 为 为 为 为 为 为 为 为 为 为 为 为 为 为 为 为 为 为 为 为 为 为 为 为 为 为 为 为 为 为 为 为 为 为 为 为 为 为 为 为 为 为 为 为 为 为 为Further, the wire adhesive resin composition of the present invention may be used by liquid-coating a space which is applied to an image-aged panel or a front panel or filled between two members to which the s is attached. When the curing reaction of the optical adhesive resin composition is carried out by irradiating a light such as a material line, if oxygen is present, the polymerization is likely to be carried out in such a case, preferably (4) to harden. The surface of the tree sap is layered with oxygen and transparent. In addition, 2 is insulated by performing polymerization under an inert environment. When such a method of isolating oxygen, the effect of oxygen can be reduced by increasing the amount of the polymerization initiator added. As the polymerization initiator to be used at this time, it is preferably phenylacetonitrile 2-[2-o-oxy-2-phenyl-ethoxycarbonyle-ethoxy]-ethene and phenylacetic acid. A mixture of 2-[2-hydroxyethoxy]-ethyl ester. The ultraviolet irradiation device is not particularly limited, and a well-known ultraviolet irradiation device i such as a one-piece type or a conveyor type can be used.

Or a metal toothed lamp. The front panel of the present invention is a front panel for an image display device. For example, a transparent protective substrate of a liquid crystal display device or the like conforms to the front panel, and may be a transparent substrate for optical use. Specific examples thereof include a plate of an inorganic material such as a glass plate or a quartz plate, a resin plate such as an acrylic plate or a polycarbonate plate, and a resin sheet such as a thick glass sheet of 201231602 HUyjjpif polyester sheet. In general, when a plastic substrate is used, the adhesion to the optical adhesive resin composition is often lowered. However, the optical adhesive resin composition of the present invention is excellent in adhesion to a plastic substrate. These front panels (transparent protective substrates) can be used in combination of a plurality of sheets, or a plurality of sheets can be used as a body. If necessary, functional layers such as an antireflection layer, an antifouling layer, a pigment layer, and a hard coat layer on the surface areas of the front panels (transparent protective substrate) may be used. The surface treatment can be performed on one side of the front panel (transparent protective substrate) or on both sides. In addition, the present invention also provides a method for attaching an optical member such as a front panel or a touch panel to a fresh panel using the optical adhesive resin composition of the present invention or an adhesive sheet.

It is also possible to use the surface layer functional layer of such an image display device. The antireflection layer exemplified as the active layer may have an antireflection property of 5% or less with respect to visible light, and a transparent substrate such as a transparent plastic film may be used by an antireflection method. ^ The layer formed. Further, the 'anti-> layer is a layer for preventing dirt from adhering to the surface, which is a material known from 201231602 HVyjjpif. Although there is no special mosquito, in order to lower the surface tension, it is preferable to contain a fluorine-based resin or the like. The pigment layer is used to reduce unnecessary light and to improve color purity. The color purity of light emitted from a panel for image display such as a liquid crystal panel is low, and jy is dissolved by light which absorbs light in an unnecessary region. In the resin, a pigment layer is formed by forming a film or laminating a base film such as a polyethylene thin film or a polyester film, or mixing the above-mentioned coloring matter by adhesion or the like. A hard coat is used to increase the surface hardness. The hard coat layer can be formed by forming a film or laminating a base film such as an amino formic acid S or an epoxy propylene or the like (tetra) acid resin or an epoxy resin: a polyethylene film. In order to laminate the optical adhesive resin composition or the optical material sheet of the present invention on a front panel, a touch panel, an image display panel, or the like, a vacuum laminator, a light layer, a single piece, which is generally used, is used. It is preferable to use a vacuum layer machine in order to suppress the bubble at the time of bonding. In addition, the paste can also reduce air bubbles by high pressure domain. The above high pressure dad treatment can be 4 (rc ~ 8 (rc (preferably ~ 70 ° C), 〇. 3 MPa ~ 〇. 8 MPa (preferably 〇 4 Mpa ~ 〇 7 m minutes ~ 60 minutes (for 丨Conditions of G minutes to % minutes) In the application of the optical adhesive resin composition of the present invention, the liquid crystal display 褒2 will be described in more detail as an example.
