Description of the invention: [Technical field to which the invention belongs] The present invention relates to an adhesive composition for a solvent-based (meth) acrylic optical member. Furthermore, the adhesive layer for optical members formed using this adhesive composition for optical members, and its manufacturing method. In addition, an adhesive optical member having the adhesive layer and an image display device such as a liquid crystal display device, an organic EL display device, or a pDp using the aforementioned adhesive optical member. The aforementioned optical components include, for example, a polarizing plate, a phase difference plate, an optical compensation film, a brightness enhancement film, and a multilayer body thereof. [Prior art] Due to the requirement for the thickness or surface uniformity of the adhesive layer for optics, high 'to make the coating good' is to use a low viscosity polymer solution for coating with low tear. However, in recent years, due to environmental considerations, it has been desired to use as few organic solvents as possible.

不使用有機溶劑之黏著劑已知有使用水系分散介質之乳膠黏著劑或者不含溶劑之uv %合型黏著劑等，但是該寺由於耐水性或膜厚均一性的問題，尚不能作為光學用。為使於聚合物濃度提高的情況下也不會造成聚合物溶劑之黏度上升，有將聚合物分子量減小的方法。然而：使用於液晶顯示裝置等之光學構件，例如偏光板或位相差板等，由於液晶元件係透過黏著劑貼附，當加 4或〜濕k光子構件的伸縮程度大，纟易於貼附後浮起或剝離。Μ 1光學構件用黏著劑既要求於加熱或增濕條 5 -200540146 件下具有耐久性並且要使分子量下降是困難的。已揭文獻有重量平均分子量10冑以下之聚合物成分含量為15 重量。/。以下之丙稀酸系聚合物作為光學黏著劑使用(例如，參考專利文獻1)。又，專利文獻2係關於聚氣乙烯樹脂㈣片材之製法， k方；塗佈帛1層及第2層片材時於有機溶膠中併用聚氯乙稀樹脂之弱溶劑及良溶劑。但是，該積層片係相當於黏著片的基材並且係使用良溶劑以提高界面的密合性，並無關於黏著劑層之形成之揭示。又，光學構件用之黏著劑為了能發揮耐久性或透明性等優點，-般係使用丙烯酸系黏著劑，並且通常會施以交聯處理以賦予適度的凝集力。該種丙烯酸系黏著劑之交聯方法會選用各種交聯劑’並且丙烯酸系聚合物官能基盥交聯化之方法之總論已被公開（例如，參照非專利文獻光學構件貼附用之黏著劑的交聯劑具體而言，已知有異氰酸酯化合⑯、環氧化合物、醛化合物、胺化合物、金 W '金料鹽 '㈣ '肼化合物等（參照專利文獻3)，尚有環氧丙基化合物、異氰酸_化合物、氮雜環丙烧化合物、金屬螯合物等（參考專利文獻4)。然而’為了使該等交聯劑發揮凝集力，必需施以一定的時效處理。通常’光學構件會在形成黏著劑層後施以狹縫加工、％穿孔加工等加工處理。如果於時效處理不充分的狀況下進行該等加X處理，由於黏著劑的凝集力不夠，黏著劑可能被切割刀帶走或是溢出切割面。也就是說，時 6 '200540146 效處理為必要者，而該掣裂長可旎會顯著地妨礙生產性。另一方面，黏著劑之交聯方法已例示者有以有機過氧化物作為橡膠系黏著南丨盥，者M與矽酮系黏著劑之交聯劑，但是，關於丙烯酸系黏著劑之六乂聯劑則並未有記載（例如，參考非專利文獻2)。丙烯酸系黏著齋I >讲$ & u ^之過乳化物交聯劑例如有由丙烯酸系共聚物與 1〜6重詈。乂益阁 > 置。乾圍之有機過氧化物之加熱反應產物所形成之膠帶黏著用έθ # ^ , … 、、成物（例如，參考專利文獻5)。此外尚有使侍配合有與丙烯酸系黏著劑於6〇〜1〇〇〇c 不會進行交聯反應之有機過氧化# ggi〜ig重量份而成之心化率未滿40重量％之黏著劑層轉印於透氣性基材上，並加熱使黏著劑軟化而含浸於基材後，#交聯得到透氣性黏著劑之方法（例如，參考專利文獻6)。Adhesives that do not use organic solvents are known as latex adhesives that use aqueous dispersion media or uv% adhesives that do not contain solvents. However, this temple cannot be used for optical applications due to water resistance or uniform film thickness. . There is a method for reducing the molecular weight of the polymer so that the viscosity of the polymer solvent does not increase even when the polymer concentration is increased. However, the optical components used in liquid crystal display devices, such as polarizing plates or phase difference plates, are attached through the adhesive. When 4 or ~ wet k photonic components are added, the degree of expansion is large, and it is easy to attach them. Floating or peeling. The adhesive for optical components of M 1 is required to have durability under heating or humidifying the strip 5 -200540146, and it is difficult to reduce the molecular weight. It has been disclosed in the literature that the content of the polymer component having a weight average molecular weight of 10 or less is 15 weight. /. The following acrylic polymer is used as an optical adhesive (for example, refer to patent document 1). In addition, Patent Document 2 relates to a method for producing a poly (vinyl chloride) resin sheet, k-square; when the first and second sheets are coated, a weak solvent and a good solvent of polyvinyl chloride resin are used in an organic sol. However, this laminated sheet is equivalent to the base material of the adhesive sheet and uses a good solvent to improve the adhesion of the interface, and is not related to the disclosure of the formation of the adhesive layer. In addition, in order to exhibit the advantages of durability and transparency, the adhesive for optical members is generally an acrylic adhesive, and is usually subjected to a crosslinking treatment to impart a moderate cohesive force. Various cross-linking agents are used for the cross-linking method of this acrylic adhesive, and a general method for cross-linking acrylic polymer functional groups has been disclosed (for example, refer to the non-patent document for adhesives for optical member attachment). Specific examples of the crosslinking agent of the agent include isocyanate compounds, epoxy compounds, aldehyde compounds, amine compounds, gold W'gold salts 'and' hydrazine compounds, etc. (see Patent Document 3). Compounds, isocyanate compounds, aziridine compounds, metal chelates, etc. (refer to Patent Document 4). However, in order for these cross-linking agents to exert cohesive force, a certain aging treatment must be applied. Usually 'Optical components are subjected to processing such as slit processing and% perforation processing after forming the adhesive layer. If such X-processing is performed under insufficient aging treatment, the adhesive may have insufficient cohesive force, and the adhesive may Taken away by the cutter or overflowing the cutting surface. In other words, the effect of 6'200540146 is necessary, and the crack length can significantly hinder productivity. On the other hand, adhesion The crosslinking method has been exemplified by using organic peroxides as rubber-based adhesives, and M and silicone-based adhesives. However, there is no such thing as acrylic adhesives. It is described (for example, refer to Non-Patent Document 2).

The content of 100 parts by weight of the monomer is about 0.001 to 0.001 parts by weight. Examples of emulsifiers used in the emulsion polymerization include sodium lauryl sulfate, ammonium lauryl sulfate, sodium dodecylbenzenesulfonate, polyoxyethylene alkyl ether sulfate, and polyoxyethylene phenyl group. Anionic emulsifiers such as sodium sulfate, non-ionic emulsifiers such as polyethylene oxide ether, polyethylene oxide benzene, polyoxyethylene fatty acid vinegar, polyethylene oxide polyfluorene oxide block polymer, etc. These emulsifiers can be used alone or in combination of two or more. Alas, Han-type emulsifiers include emulsifiers that introduce free radical polymerizable functional groups such as acrylic and allyl ether groups. Specifically, for example, Aku'alon HS-10, HS, 20, KH-IO , Rr BC-05, BCM〇, BC_2〇 (manufactured by Daiichi Kogyo Co., Ltd.), Adekali Aso f s_ (manufactured by Asahi Chemical Co., Ltd.), etc .: Since the reactive emulsifier will be embedded in the polymerization chain after polymerization, Will make water resistant H Ai good "car 乂 said better. The amount of the emulsifier used is 0.3 to 5 parts by weight based on 100 parts by weight of the monomer. From the viewpoint of polymerization stability or mechanical stability, 19 200540146 0.5 to 1 part by weight is preferred. In order to easily balance the adhesiveness, the glass transition temperature (Tg) of the (meth) acrylic polymer is 0 ° c or lower (usually -100T: or higher), and more preferably -10C or lower. If the glass transition temperature is higher than 0 ° C, the polymer will not easily flow and cause insufficient wetting of the polarizing plate, which may cause swelling between the polarizing plate and the adhesive composition layer of the adhesive sheet. The glass transition temperature (Tg) of the (meth) acrylic acid polymer can be adjusted within the aforementioned range by appropriately changing the monomer component or composition ratio used. The adhesive composition for an optical member of the present invention is based on the (meth) acrylic polymer as described above. Regarding the solubility theory, Hildebrand proposed the basic theory of solubility and solubility parameters from 1936 to 1950 (J midebrand, RL. Sc〇u The Soluability of Nonelectrolytes, Rheinhold, NY (1950)). According to this theory, when two substances When i and 2 are mixed, the mixed entropy (Enthaipy) is as follows. ΔΗ = νΐ (δ1-δ2) 2φ22 Here, VI is the mole volume of substance i, δ1 and δ2 are the SP values of substance i and substance 2 'Φ2 is the volume fraction of substance 2, when δ1 and δ2 are equal or close Dissolution will occur. In the present invention, the solubility of a homopolymer is not a solvent (good solvent) which is easily miscible with a (meth) acrylic polymer, but a homopolymer (the one with the largest content) constituting the main monomer unit of the (meth) acrylic polymer. When the parameter (sp value) is δι "(J / cm3) ^", the difference between the solubility parameter (sp value) (△ 卜幻-以) can be a solubility parameter (sp value) of + 1 · 7 ~ + 5 Weakness of δ2 "(J / cm3) 1/2" 20 • 200540146 The solvent content is 20 to 60% by weight of the total organic solvent. The difference in solubility parameter (SP value) = more preferably +2 to +5. By adding a predetermined amount of this weak solvent, the viscosity of the adhesive composition can be reduced. The SP values of various solvents can be easily calculated from the latent heat of evaporation or the boiling point. The measurement of the SP value (solubility parameter) of the polymer includes, for example, the measurement of the intrinsic viscosity of the polymer, the measurement of the cloud point when a non-solvent is dripped into the diluted solution of the polymer, and the measurement of the maximum swelling ratio of the polymer in various solvents. The SP value of the (meth) acrylic polymer of the present invention is the SP value in Table 1 (the measured value of the maximum swelling ratio contained in the reference φ).

In the present invention, if a weak solvent is added, the viscosity decreases, so that a good coating surface can be obtained by using a small amount of solvent. However, in the (fluorenyl) acrylic polymer of the present invention, if the amount of the weak solvent exceeds 60% by weight of all organic solvents, the polymer may be precipitated and the coating may not be applied. In the present invention, the content of the weak solvent is 22 to 200540146 20 to 60% by weight of the total amount of the organic solvent, but preferably 40 to 55% by weight, and most preferably 40 to 50% by weight. When a weak solvent having a plural Δδ in the above range is used, the total content of the contents of the respective weak solvents is preferably within the above range. As a method for measuring the degree of extension of a polymer chain, a multi-angle scattering (MALLLS) method can be used. The measurement step is first to change the polymer concentration to determine the refractive index 'to obtain dn / dc. Then, the MALLLS measurement was performed in a microbatch, and a z-mean-square rotation radius (Rz) was obtained with a Zimm plot. The measurement of the refractive index of the solvent was performed with a device: Adago, Abbe refractometer, and wavelength: 589 nm. As for the measurement device, a GPC garment was used for the micro batch measurement, but the GPC column was connected to a stainless steel tube. MALLS only double test fast.

If it is more than 0.02 weight I, the physical properties may be deteriorated, and if it is less, the crosslinking reaction is insufficient, and the adhesion may be deteriorated. Both: 2 parts by weight. When used as a starting material for polymerization, the remaining peroxide that is not used in the polymerization reaction can be used for the inventory quantification and the f + H ^ reaction. In this case, the residual amount can be used. And add two deniers as needed to use. In 77, the half-life of the peroxide is the index of the rate of decomposition of peroxy ^ and lice, which refers to the time when the residual amount of peroxide reaches half of the total, such as A, and T. To obtain the solution temperature or the temperature at any time of half a month / month # ,,, w σday # ,,, The half-life of the degree is recorded in the manufacturer's product catalog, for example, the Japanese oil version (May 2003 )"Wait. The method for measuring the residual peroxide decomposition amount after the 9th reaction treatment of the organic peroxide catalog can be performed by, for example, HPLC (Shangsu Liquid Chromatography). Although the mechanism for the peroxide to form a cross-link is not clear, it is estimated as follows. : Emulsion cross-linking will first generate aeration of the polymer skeleton through the free radicals (active sources) generated by peroxides, ^ ^ The tick reaction will cause the polymer skeleton to generate free radicals.物骨牟卜 6 ^ The free radicals on the wood will form crosslinks by coupling, so that the entire skeleton of the t-composite is embedded in the cross-linking structure, so that the entire adhesive is uniformly cross-linked + its, and fruit are in the parent link Immediately after processing, processing such as perforation processing is performed. The yueyue dagger is used to prevent the adhesive from attaching to the cutting knife or to prevent post-processing and other effects. With the 6 ^ ^ treatment without parental shame, the cross-linking reaction does not progress. Stabilizing characteristics. The adhesive composition of the present invention can obtain better heat resistance by cross-linking the (meth) acrylic poly 29 • 200540146 compound with a peroxide, and can be used in combination with other cross-linking agents. Crosslinking agents generally use carboxylic acid groups of (fluorenyl) acrylic polymers and polyfunctional compounds that can react with other functional groups to form a crosslinked structure. Examples of the crosslinking agent used in the present invention include polyisocyanate compounds, epoxy compounds, oxazoline compounds, melamine-based resins, aziridines, and metal chelate compounds. Among them, from the viewpoints of improving the adhesive properties and improving the fixing force of the optical member and the polarizing plate, it is preferable to use a polyisocyanate compound. In particular, when manufacturing acrylic polymers, copolymerize with acrylic acid-containing hydroxyl-containing monomers, such as acrylic acid, to introduce hydroxyl groups in acrylic polymers. It is preferable to use polyisocyanate as a crosslinking agent to form Crosslinked structure of acrylic polymer. These compounds may be used alone or in combination. A polyisocyanate-based cross-linking agent refers to an isocyanate compound having two or more isobaric acid groups (with isocyanate groups as block agents and containing isocyanate-regenerating functional groups temporarily protected by digitization or the like) in one molecule. Examples of the isocyanate compound include aromatic isocyanate g, such as fluorene phenylene diisocyanate, di: benzene diisocyanate g, isophoric diisocyanate ^ cycloaliphatic isocyanate, hexamethylene Aliphatic isocyanates such as diisocyanates, and diisocyanate adducts of various polyols.

The optical member of the present invention is, for example, a reflection plate or a transflective plate, a phase difference plate (including a wavelength plate such as 1/2 or 1/4), a viewing angle compensation film, and a brightness enhancement film. Floor. These can be used alone as the optical member of the present invention, or they can be laminated on the polarizing plate in the above-mentioned practical use. In particular, an ellipse formed by further stacking a reflective polarizing plate or a transflective polarizing plate formed by further stacking a reflective plate or a transflective reflective plate on a polarizing plate, and further stacking a phase difference plate on the polarizing plate is preferable. A polarizing plate or a circular polarizing plate; a wide-viewing angle polarizing plate further laminated with a viewing angle compensation film on the polarizing plate, or a polarizing plate further laminated with a brightness enhancing film on the polarizing plate. A reflective polarizing plate is provided with a reflective layer on the polarizing plate, and is used to form a type of liquid crystal display device that reflects incident light from the visual side (display side) for display. Τ omits a built-in backlight and other light sources. It is easy to reduce the thickness of the liquid crystal display device. When forming a reflective polarizing plate, a reflective layer made of metal or the like can be attached to one side of the polarizing plate, such as through the translucent 4 layers, if necessary. ^ = Is a specific example of a reflective polarizing plate, and can be provided with a box or steamer made of reflective metal such as Ming on one side of a transparent protective layer (so τ may be required). Those who form a reflective layer by plating, etc., may also include fine particles in the front and rear moon-retaining layers as a fine uneven structure on the surface, and a reflective layer with a fine uneven structure provided thereon. The aforementioned fine uneven structure can prevent orientation by irregularly reflecting and diffusing incident light. 41 • 200540146 The appearance of sex and flicker, and the ability to suppress bright and dark streaks are its advantages. A transparent protective layer containing fine particles can be diffused when incident light and its reflected light pass through, and it can further suppress bright and dark streaks, which is also an advantage. The formation of the reflective layer with the fine uneven structure reflecting the fine uneven structure on the surface of the transparent protective layer can be carried out by using an appropriate evaporation method such as a vacuum evaporation method, an ion implantation method, a money splash method, or a plating method. This method is implemented by directly attaching a metal to the surface of the transparent protective layer. In addition to the reflective plate being directly attached to the transparent protective layer of the aforementioned polarizing plate, a reflective sheet formed by providing a reflective layer on an appropriate film having the transparent film as a framework can also be used. In addition, since the reflective layer is usually made of metal, the reflective surface is used in a state of being covered with a transparent protective layer or a polarizing plate. From the viewpoint of preventing long-term continuation of the reflectance due to oxidation and the initial reflectance, , Or the consideration of avoiding the setting of an additional protective layer is better. The semi-transmissive polarizing plate can be obtained by providing a semi-transmissive reflective layer such as a semi-lens that reflects light on the reflective layer and transmits light. Semi-transmissive polarizers are usually installed on the inside of liquid crystal elements, and can be used to form the following types of liquid crystal display devices: When the liquid crystal display device is used in a relatively bright environment, it is from the visual side (display side) Reflecting incident light to display an image 'In a relatively dark environment, a person using a built-in light source such as a backlight built into the inside of the transflective polarizer to display the image. That is, the semi-transmissive polarizing plate can be used in a bright environment to save energy used by a light source such as a backlight. In a relatively dark environment, a liquid crystal display device of a built-in light source type can be used. 42 • 200540146 Next, the elliptical or circular polarizer formed by further laminating the retardation plate on the polarizer will be described. In order to convert linearly polarized light to elliptically or circularly polarized light, or to convert elliptical or circularly polarized light to linearly polarized light, or to change the direction of linearly polarized light, a retardation plate or the like is required. In particular, as a retardation plate that converts linearly polarized light into circularly polarized light or circularly polarized light into linearly polarized light, a so-called 1/4 wavelength plate (also referred to as a λ / 4 plate) can be used. The 1/2 wavelength plate (also known as the λ / 2 plate) is usually used to change the polarization direction of linearly polarized light.

Examples of examples of side-chain liquid crystal polymers include polysiloxane, polyacrylate, polymethacrylic acid, and polyacrylic acid as the main bond backbone. The spacer composed of a cluster has a liquid crystal base composed of units of Wei compounds which are substituted by para-positions imparting nematic alignment. These liquid crystal polymerizations can be performed by, for example, applying a rubbing treatment to the surface of a special film formed of polyimide or polyvinyl alcohol formed on glass, or aligning those formed by oblique vaporization of oxidized stone. On the treatment surface, the solution of the liquid crystal polymer is expanded to perform heat treatment. …… A retardation plate may be used for compensating the coloring or viewing angle caused by the refraction of various wavelength plates or liquid crystal layers, etc., and having an appropriate retardation according to the purpose of use. At least two types of retardation plates are laminated to control optical characteristics such as retardation. The above-mentioned elliptically polarizing plate and reflective elliptically polarizing plate are those obtained by laminating a polarizing plate or a combination of a reflective polarizing plate and a retardation plate in an appropriate combination. The elliptical polarizer and the like can be formed by laminating them sequentially in the manufacturing process of the liquid crystal display device by combining a (reflective) polarizer and a retardation plate, but as described above Those who have previously made optical films such as rounded polarizing plates are excellent in quality stability and stacking workability, so they can improve the manufacturing efficiency of liquid crystal display devices and the like. The viewing angle compensation film is a film used to make the daylight surface of the liquid crystal display device see the image more clearly even when the daylight surface of the liquid crystal display device is not perpendicular to the daylight surface. Examples of such a viewing angle compensation retardation plate include a retardation plate, an alignment film of a liquid crystal polymer, or the like, or an alignment layer that supports a liquid crystal polymer on a transparent substrate. A common retardation plate is a polymer film with birefringence that is uniaxially stretched along its plane direction. In contrast, a phase object that is a viewing angle compensation film is used. Polymerization with birefringence II: A polymer film is stretched in the direction of the plane, and the polymer film is stretched in two directions like an oblique alignment film in the thickness direction. For example, the polymer film is bonded to the polymer film. 、 = Oblique alignment film, the functions that can be cited,… thin film, stretch the polymer under the action of heat to generate shrinkage, polymer oblique alignment, shrinkage treatment, or make liquid ^ ^ ^ ^, phase The raw polymer of the difference plate can be the same as the polymer described in the difference plate. It can be used to reduce the change in the viewing angle of the eye due to the phase I square color caused by the liquid crystal element. Caused by the purpose of expanding the eyes of a good visual angle. Also, to achieve a broader good purpose for triethyl cellulose-based cellulose test, 'the better one can be proton anisotropic layer (45 * 200540146 alignment layer of liquid crystal polymer, especially dish liquid crystal polymer). The optically-compensated retardation plate formed by the inclined alignment layer). A polarizing plate formed by adhering a polarizing plate and a brightness enhancing film is usually used inside a liquid crystal element. The brightness enhancement film exhibits the following characteristics: When natural light is incident due to the backlight of a liquid crystal display device or reflection from the inside, etc., it can reflect linearly polarized light of a predetermined polarization axis or circularly polarized light of a predetermined direction and transmit other light. Therefore, a polarizing plate laminated with a brightness-enhancing film and a polarizing plate can allow light from a light source such as a backlight to be incident to obtain a penetrating light in a predetermined polarization state, and prevent light from passing through outside the predetermined polarization state. reflection. The light reflected on the surface of the brightness-enhancing film passes through a reflective layer provided on the rear side of the brightness-increasing film, and then is incident again on the brightness-enhancing film, so that a part or all of the light is transmitted in the form of light in a predetermined polarized state to seek Increasing the amount of light transmitted through the brightness-improving film and supplying polarized light that is not easily absorbed by the polarizing film 'increases the amount of available light such as liquid crystal image display to increase brightness. That is, in the case where a brightness-improving film is not used, and the light is incident from the inside of the liquid crystal element through a polarizing film with a backlight or the like, most of the light whose polarization direction is inconsistent with the polarization axis of the polarizing film will be absorbed by the polarizing film, and Does not pass through the polarizing film. That is, although the characteristics of the polarizing film will vary depending on the use, roughly 50% of the light will be absorbed by the polarizing film, which reduces the amount of light available for liquid crystal display devices and the like, and darkens the image. The brightness-enhancing film can prevent the light in the direction of the polarized light absorbed by the polarizing film from hitting the polarizing film, and reflected by the brightness-enhancing film, and then re-entering the brightness-enhancing film through the reflection layer provided on the rear side, and so on. Only the light reflected and folded back between the two can be transmitted through the polarized light in the polarizing direction of the polarizing plate, and the light is supplied to the polarizing film. Therefore, the backlight and other light can be effectively used in the liquid crystal display device. The display of the image makes the image bright. A diffusion plate may also be provided between the exemption-improving film and the reflective layer. The light in the polarized state reflected by the brightness-enhancing film is directed toward the above-mentioned reflective layer, and a diffuser plate is provided to uniformly diffuse the passing light and eliminate the polarized state into a non-polarized state. That is, the original natural light state is restored. The light in this non-polarized state (that is, the state of natural light) travels toward the reflective layer, etc., is reflected through the reflective layer, and then enters the brightness enhancement film through the diffusion plate, so as to be repeated in this manner. By setting a diffuser plate to restore the original natural light state, the brightness of the display screen can be maintained, and the unevenness of light and dark on the display daytime can be reduced, and a uniform and bright picture can be provided. It is generally believed that by providing a diffuser to restore the original state of natural light, the initial incident light can increase the number of reflections to increase the number of reflections, which can complement the role of the diffuser to provide a uniform and bright display screen. . As the above-mentioned party enhancement film, for example, a multilayer film of a dielectric body or a multilayer laminate of a film having a different refractive index anisotropy can be appropriately used, and it is impossible to achieve linear polarization through a predetermined polarization axis. Those that reflect other light; those that support a cholesteric liquid crystal polymer or its alignment liquid crystal layer on a film substrate, show that it can reflect circular polarization of either left-handed or right-handed and make other The characteristics of light transmission. Therefore, the brightness k-liter film of the type that allows a linearly polarized light of a predetermined polarization axis to penetrate, by aligning the transmitted light with the polarization axis and entering the polarizing plate, the loss absorbed by the polarizing plate can be suppressed and can be efficiently worn through. On the other hand, the brightness of the type that allows circularly polarized light to pass through like a cholesterol-type liquid crystal layer is improved. It is preferable to linearly polarize through a retardation plate and then enter the polarizing plate. In addition, by using a quarter-wave plate, circularly polarized light can be converted into linearly polarized light. A retardation plate having a 1/4 wavelength plate function in a wide wavelength range such as a visible light range can be used for a retardation layer that functions as a 1/4 wavelength plate to a monochromatic light having a wavelength of 5 5 Onm, and display other phases. A retardation layer having a difference characteristic (for example, a retardation layer that functions as a 1/2 wavelength plate) is obtained by overlapping. Therefore, the retardation plate disposed between the polarizing plate and the brightness enhancement film may be composed of one retardation layer or at least two retardation layers. Furthermore, the cholesterol-type liquid crystal layer can be obtained by combining two or at least three layers of overlapping structures with different reflection wavelengths to obtain a circularly polarized light reflection in a wide wavelength range such as the visible light range, thereby obtaining a wide wavelength range. It penetrates circularly polarized light.

Therefore, it may be a reflective elliptical polarizer or a semi-transmissive elliptical polarizer formed by combining the above-mentioned reflective polarizer or semi-transmissive polarizer with a phase difference plate. The optical components formed by laminating the aforementioned optical layers on a polarizing plate can be formed sequentially in a layer-by-layer manner during the manufacturing process of a liquid crystal display device and the like. It is superior in terms of composition, so it can improve the process of liquid crystal display devices, etc., and it is an appropriate bonding means for the implementation of the layering of the advantages of the potted layer. Second, when the aforementioned polarizing plate is bonded to other optical layers, it can make the optical The axis makes an appropriate arrangement angle according to the phase difference characteristics of the required purpose. Each layer of Ben Maoming's adhesive-type optical member or adhesive layer can be, for example, a salicylic acid-based compound or a benzophenone-based compound, a benzotrisialylated D substance or an cyanoacrylate-based compound, or a nickel salt. UV absorbing agents such as compounds are treated so as to have ultraviolet absorbing ability.

The formation of a liquid crystal display device can be performed in accordance with conventional methods. That is, a liquid crystal display device is generally formed by appropriately assembling a liquid crystal element with an adhesive optical component and a structural component such as a lighting system as needed, and adding a circuit to form the component. The invention is not particularly limited except that it is necessary to use the optical member of the present invention, and a known structure can be used. The liquid crystal element can be in any form such as a 'TN type, STN type, and redundant type. The liquid crystal display device may be formed on one or both sides of the liquid crystal element with an adhesive type optical member, or a suitable liquid crystal display device using a backlight or a reflection plate in an illumination system. In this case, the optical member of the present invention may be provided on one side or both sides of the liquid crystal element. If the optical members are provided on both sides, they may be regarded as the same optical members or different. When forming a liquid crystal display device, appropriate components such as a diffusion plate, an anti-glare layer, an anti-reflection film, a protective plate, a prism row, a lens row sheet, a light diffusion plate, and a backlight can be provided at appropriate positions. Wait. Next, an electroluminescence device (organic EL display device) will be described. Generally, an organic EL display device has a transparent electrode, an organic light-emitting layer, and a metal electrode laminated on a transparent substrate in order to form a light-emitting body (organic electroluminescent body). Here, the organic light-emitting layer is a laminate of various organic thin films. ^ 49 200540146 It is known that, for example, a hole-implanted layer made of a triphenylamine derivative, etc .: Properties: a light-emitting layer made of organic solids. : Luminescent ΐ :: Laminated body made of electron implanted layers composed of naphthalene derivatives: or various combinations of hole implantation layers and luminescent layers. The laminated body of the implanted layer, etc .: The EL device is usually based on the following principles to emit light. That is, the energy generated by applying the = electrodes to the organic light-emitting layer to the holes and the recombination of the electrons will excite the fluorescent substance that is excited to emit light when it returns to the ground state. Midway again :: This mechanism is the same as a normal diode, and it can be inferred that ρ and the luminous intensity material are applied to show the strong non-linearity with rectification. The smaller one, in the organic EL device, The light is derived from the organic light-emitting layer. The electrodes on the two sides must be transparent electrodes. Usually, a transparent electrode formed of indium tin oxide (called a square transparent conductor) is used as the anode. The other side is to make # 1 子植It is easy for people to improve the luminous efficiency. It is important for the cathode to use a small work function and a small shell. Generally, metal electrodes such as Mg-Ag and _Ll can be used. In the organic EL device constituted, the organic light emitting layer is usually used. It is a thin film formed to a thickness of about 10 nm. Therefore, the organic light emitting layer and the transparent electrode can also make

Therefore, when non-emissive, the #% U clothes from the transparent substrate penetrates the transparent electrode and the organic light-emitting layer and is reflected at the metal electrode. * * ^ &Amp; especially, will be emitted to the surface side of the transparent substrate again Therefore, when viewed from the outside, I am deaf, and the display surface of the organic EL device will be mirrored. 50 200540146 D3 organic light emitting device (Organic EL1 display device with the reading side + electrode on the side of the organic light emitting body that emits light by applying voltage, and the back side of the organic light-emitting layer) can also be used. For example, a polarizing plate is placed on the surface side of the transparent electrode, and a retardation plate is provided between the transparent electrode and the polarizing plate. The retardation plate and polarizing plate have the effect of reflecting the light reflected from the external electrode. Φm The company's role is to give priority to the effect, so the polarizing effect can be used to identify the mirror surface of the metal electrode from outside. . In particular, the second step is to form a retardation plate with a 1/4 wavelength plate and the angle between the polarizing plate and the polarizing direction of the retardation film. The face of the electrode is completely covered. That is, the external light incident on the organic EL display device can pass through only a linearly polarized component using a polarizing plate. This linearly polarized light can be generally elliptical polarized light through a retardation film, but when the retardation film is a 1/4 wavelength plate, the polarization direction of the plate and the retardation film & & Xiao〇 is 7Γ / 4, It will become circularly polarized. This circularly polarized light usually penetrates the transparent substrate, the transparent electrode, and the organic thin film, and is reflected at the metal electrode 'and penetrates the organic thin film, the transparent electrode, and the transparent substrate' again to be linearly polarized by the retardation film. This linearly polarized light cannot pass through the polarizing plate because it is orthogonal to the polarization direction of the polarizing plate. Therefore, the mirror surface of the metal electrode can be completely shielded.

如表4之結果可得知，本發明之光學構件用黏著劑層製造方法即使減少溶劑量仍能以低黏度得到良好塗佈面，且耐久性良好。而比較例之光學構件用黏著劑層製造方法黏度高，不能均勻的塗佈，或者溶液不均勻，很難得到良好的塗佈面。又，如果降低（甲基）丙烯酸系聚合物之分子量，黏度可降得非常低，伴隨於此，耐久性也會變差。而， 63 -200540146 如果改變（甲基）丙烯酸系聚合物使Δδ低於+ 1·7，無法得到良好的黏度降低效果。 [實施例II] <過氧化物之分解量（分解率）測定> 熱分解後過氧化物之分解量（分解率）係依如下以 HPLC(高速液體層析）測定。分別取出分解處理前後之黏著劑組成物約〇.2g，浸泡於乙酸乙酿10ml，以振盪機於25°C、120rpm進行3小時 φ 振盪萃取後，於室溫靜置3天。其次，加入乙腈10ml，於 25°C、120i*pm振盪30分鐘，將以濾膜（0.45 // m)過濾得到之萃取液約10// 1注入HPLC進行分析，以分解處理前後之過氧化物量變化做為過氧化物分解量。分解處理後之值P!(g)除以分解處理前之值PG(g)的比值[(P】/作為過氧化物分解率（％)。分析裝置：東索公司製，HPL CCPM/UV8000 管柱： Φ 樣本管柱：NUCLEOSIL 7C18(MACHEREY-NAGEL 公司製，4.6mm(|)x250mm) 流量·· 1 .Oml/min 管柱壓力·· 4 1 kg/cm2 管柱溫度：40°C 洗提液：水/乙腈=30/70 注入量：1 0 // 1 注入試樣濃度：0.01重量％ 64 200540146 檢測器：UV檢測器（230nm) <膠化率之測定> 將各實施例、比較例製作之黏著劑層取出約W,g(約 0」g)，於室溫（約25°C )浸泡於乙酸乙酯1週。之後，從乙酸乙酯中取出經浸泡處理的黏著劑層，於i 30°C乾燥2小時後，測定重量Wj，以（界2/冒】）\1〇〇(重量％)得出之值作為膠化率（重量％)。 <黏度之評價> •所製作黏著劑溶劑之黏度係使用黏度計（東機產業公司製，TV-20型，紡錘型），依以下條件測定。轉子：THH-14 旋轉數：1 Orpm 剪切速度：2.5/s 測定溫度：23°C <塗佈性之評價>As can be seen from the results in Table 4, the method for producing an adhesive layer for an optical member of the present invention can obtain a good coated surface with a low viscosity even with a reduced solvent amount, and has excellent durability. In contrast, the method for producing an adhesive layer for an optical member of the comparative example has high viscosity and cannot be uniformly coated, or the solution is not uniform, and it is difficult to obtain a good coated surface. In addition, if the molecular weight of the (meth) acrylic polymer is reduced, the viscosity can be reduced very low, and the durability is also deteriorated with this. However, if 63-200540146 changes the (meth) acrylic polymer to make Δδ lower than +1.7, a good viscosity reduction effect cannot be obtained.
