Description

[Technical Field] The present invention relates to an adhesive composition suitable for bonding when an optical member used in an image display device such as a liquid crystal display device is produced, and the use of the same A laminate body and a display device of the composition. [Prior Art] In recent years, with the remarkable improvement in display performance such as fineness and contrast of liquid crystal display devices, there has been a great improvement in the so-called long-term durability such as resistance to harsh environments and prolonged driving time that can be used. . The performance of the projection type liquid crystal display device has also improved, but at the same time, new problems have arisen. As a result of achieving a high contrast projection image, it is possible to observe the unevenness of the optical member which cannot be discerned by the low contrast image. In particular, the unevenness caused by the polarizing plate is extremely significant for the highly contrasted projected image, and the heat generated when the light passes through the polarizing plate causes the thermal birefringence of the cellulose triacetate film used as the protective plate. Further, the physical thermal strain of the film is matched, so that the cellulose acetate film which is originally disposed so as not to affect the linearly polarized light has a phase difference and an optical axis which affect the linearly polarized light, and becomes a cause of unevenness of the projected image. The polarizing plate is a structure in which a protective plate is bonded to one side or both sides of a polarizing element. In the present invention, the terms "substrate" and "film" are not used accurately. The term "film" is usually used for soft and thin films. However, as mentioned above, in the term "protective plate", although "plate" is used, "cellulose triacetate" used as a "protective plate" is generally called "film", so "film" is used as described above. The term. Therefore, the film is not only a soft and thin film of 4 321 713 201033312, but also a thin film even if it is not so soft. Further, "substrate" or "plate" means a rigid plate-shaped molded body which is relatively soft in flexibility or which is completely or hardly flexible. • In addition, as the projection type liquid crystal display device is strongly required to be miniaturized, high-definition, and high-brightness, it is necessary to select a high-output lamp to expose the cellulose triacetate film of the protective plate to a high-light amount of light. The problem of deterioration of the film itself. In order to solve such a problem caused by the protective sheet, there is a method of replacing the cellulose triacetate film with a protective sheet which is hard to generate thermal birefringence and which is highly resistant to heat. A protective sheet satisfying this property, for example, a light transmissive inorganic substrate such as an inorganic glass plate, a crystal plate or a sapphire plate. A method of bonding a polarizing element to an inorganic substrate such as an inorganic glass plate, a crystal plate or a sapphire plate is preferably a photocurable type adhesive having an advantage of suppressing the influence of an optical member which is not resistant to high heat to a minimum. method. Further, there is a method of using an adhesive suitable for processing of an optical member. © The present inventors have carefully studied the problem of unevenness in projected image, and found that when an inorganic substrate is directly bonded to a polarizing element by a conventional photocurable adhesive or an adhesive, triacetic acid is generated. The cellulose film used as a protective sheet was not observed in the polarizing plate due to the problem of the bonding layer. This is a change in appearance and deterioration in performance of the polarizing element. The polarizing plate or the polarizing element is bonded to an inorganic substrate such as inorganic glass, sapphire or crystal, and is known as Patent Documents 1 to 5. Patent Document 1 and Patent Document 2 disclose a configuration of a holding plate using a sapphire plate as a polarizing plate. In order to prevent deterioration of the polarizing plate used in the projection type liquid crystal display device 5 321713 201033312 due to light and heat, the sapphire substrate having high thermal conductivity is attached to the polarizing plate under the idea of improving the cooling efficiency of the air cooling fan. Improve the display of enamel. However, there is no detailed description about the bonding layer. The change in appearance which the inventors regarded as a problem and the durability of the long-term polarizing plate are not mentioned and are ignored. Patent Document 3 discloses a configuration in which a substrate having a high thermal conductivity is bonded to one surface (one surface opposite to the liquid crystal light valve) of a polarizing plate used in a projection type liquid crystal display device. Further, Patent Document 4 discloses a configuration in which a glass plate is bonded to at least one surface of a polarizing element and combined with an ultraviolet shielding filter or a light sheet. These techniques are the same as those of Patent Documents 1 and 2, and aim to prevent deterioration of the liquid crystal light valve and the polarizing plate by improving the air cooling efficiency. However, neither has a detailed description of the material of the bonding layer, and the problems caused by the bonding layer are ignored. Patent Document 5 discloses a configuration in which an inorganic material is bonded to both sides of a polarizing plate. In the projection type liquid crystal display device, by suppressing the decrease in the polarization characteristics of the polarizing plate and bonding the sapphire plate or the crystal substrate at an appropriate angle, the cellulose triacetate film can be obtained as a ruthenium protection plate. When the quality is displayed for a higher projection. However, when a photocurable adhesive or an adhesive is used for bonding, it is only slightly described, and the problem that the present inventors have found that is caused by the bonding layer is still neglected. In the prior art, an inorganic substrate is bonded to a polarizing plate or a polarizing element as a heat dissipating plate to improve heat, and the display quality of the projection type liquid crystal display device is improved, and the deterioration of the polarizing plate over time is suppressed, but the cause is caused. The problems with the fit layer are ignored. [Patent Document 1] [Patent Document 2] [Patent Document 3] [Patent Document 4] [Patent Document 5] [Summary of the Invention] Japanese Patent No. 3091283 (page 2-4) 曰本特开Japanese Patent Publication No. 2006-276617 (page 2-4) 曰本专利3049752 (page 2-3) 曰本特开平10-39138号 (page 2-4) 曰本特开2008-51995号(Pages 3-6) (Problems to be Solved by the Invention) The present inventors have carefully studied the bonding of a light-transmissive inorganic substrate and a polarizing element in order to improve the problem of unevenness in projected images, and found that In the case of known photocurable adhesives, since the compound of the adhesive layer accelerates deterioration due to the influence of the polarizing element, the durability of the polarizing plate is remarkably lowered, and the adhesive layer is caused by hardening shrinkage. In addition, when the conventionally known adhesive is used, the durability is not extremely lowered, but the adhesive layer is heated and easily peeled off. Further, in the polarizing plate using the inorganic substrate to which the conventionally known photocurable adhesive is bonded as a protective sheet, the inorganic substrate hardly causes heat shrinkage with respect to low heat shrinkage == Liquid crystal display device In the case where the temperature of the polarizing plate rises, the worst case causes breakage of the polarizing element, which causes a deterioration in the appearance of the bonding layer and a problem that the performance of the plate is lowered. The deterioration of the appearance of the bonding layer and the deterioration of the performance due to the breakage of the polarizing element significantly deteriorate the display performance of the projection type liquid crystal display device. Therefore, the problem of improvement is strongly desired. (Means for solving the problem) 321713 7 201033312
