[Prior Art] In recent years, there have been cases where a liquid crystal display panel is used as an in-vehicle or a smashable information device, and an adhesive for bonding a polarizing plate constituting a liquid crystal display panel to an input member is strongly required to have excellent adhesion. Force, refractive index control or high transparency. In general, a method of manufacturing a display element and an input element includes a method of incorporating an input element into a display element (In-Cell), and a method of bonding an input element to a display element by bonding (external type ( On-Cell)). The former's built-in requires complicated processes or precise steps, and the latter has the advantage of saving production costs by making only input elements and display elements and bonding the two. In order to bond the input member to the display element substrate, a double-sided tape or a photocurable adhesive is used. There is a method of providing a transparent control panel with a double-layer adhesive having a thickness of 0.3 mm to 1 mm on the outer periphery of the display element. Further, there is a method in which a touch panel is entirely attached to a display element by a photocurable adhesive. By comprehensively fitting, the gas layer between the display element and the Φ plate or the cover plate is replaced by a photocurable adhesive, so that the reflection on the interface with the air layer is reduced and the enamel is improved. * The refractive index of the photo-curing recording agent is preferably the same as the refractive index of the panel or cover. When the adhesive is used as a photocurable adhesive, it is known to apply a coating on the display element with a thickness of about 丨 axis. 201221603 ^^/υ,> ριι adhesive, the money is bonded to the cover plate Method (for example, know patent 1). Gel or rubber-like dot-bonding agents can also be used as the binder. ί 1 has a method of bonding the display element to the control panel in the atmosphere so as not to cause the bubble to enter in the atmosphere (for example, refer to Patent Document 2). In addition, there is also a method of splicing and splicing the splicing of the splicing of the smear. It is known that the adhesive sheet of == ί Tr _ is such that the display element and the touch panel are laminated and attached so as not to allow air bubbles to enter the bonding surface. Method (for example, refer to Patent Document 3). Further, a transparent adhesive sheet having a thickness of 12 in the (4) adhesive layer of o·1 mm is used as a transparent adhesive sheet having a repairing property and a shock absorbing property, so that the display member and the cover sheet are attached. 4). The shortcomings of the law (such as the failure to order repair (repost). Therefore, it is strong. It has high transparency, adhesion between display components and input components, etc., and has a repairable graded adhesive. , a transparent adhesive film having the same refractive index as that of the material to be bonded.

Thus, it was confirmed that the refractive index was controlled by the use of the filler (D). Further, in Examples 12 to 23, and Examples 35 to 50, by using such a filler (D) in combination with a radical polymerizable monomer (B), it is also possible to obtain a free radical from a glass or a TAC film.

[Comparative Example 1 to Comparative Example 28] The components of B to F described in Table 5 were used in the same manner as in the examples, except that the cellulose derivative (component A) was not used. The blending amount (wt%) was mixed and searched off to obtain a comparative chemical adhesive. Further, the viscosity, light transmittance, refractive index, adhesiveness, and the obtained repairing adhesive were also evaluated in the same manner as in the examples.

Industrial Applicability Various display elements such as β-liquid crystals are used for various purposes, and not only improvement in image quality but also improvement in productivity is required. In the present invention, in the manufacture of a full-adhesive-indicating element requiring an optical element, an adhesive film having a refractive index substantially the same as that of a transparent member of a substrate or a mask which is generally used for an optical 7G member can be formed, _^ There is no degradation in the image quality caused by the difference in refractive index. Further, in the present invention, since such an adhesive film can be formed by a simple operation of light irradiation, the workability of the display element can be improved. Further, in the present invention, since the formed adhesive film can be formed from the optical element, Therefore, the discarding of defective products caused by the failure of _ can be reduced, so that the yield of the display element can be further improved. Thus, the present invention is expected to contribute greatly to the improvement of both the production and the production of the hemp element. Although the present invention has been disclosed in the above embodiments, it is not intended to limit the invention, and any one of ordinary skill in the art can make some modifications and refinements without departing from the spirit and scope of the invention.
