Membrane and the like. More specifically, the present invention relates to an adhesive composition which exhibits excellent durability even under high temperature and high humidity and which is excellent in suppressing generation of white spots. [Prior Art] A liquid crystal display device is generally composed of a liquid crystal cell in which a liquid crystal component oriented in a predetermined direction is sandwiched between two supporting substrates such as glass, and an optical film which is polarized. Film or retardation film, brightness enhancement film, and the like. When these optical films are laminated to each other and the optical film is adhered to the liquid crystal cell, an adhesive is often used. The liquid crystal display device is widely used as a display device such as a personal computer, a television, or a car navigation. These are also sometimes used in harsh environments like high temperatures and high humidity. Therefore, it is required to develop an adhesive which is excellent in durability, and even if it is used for a long period of time, peeling and bubble generation do not occur, etc. Further, for example, in a severe environment like high temperature and humidity, the shrinkage of the optical film and Dimensional changes in expansion can become severe. Conventional adhesive layers do not alleviate the stress caused by such dimensional changes, and the residual stress of the optical film becomes uneven. As a result, the so-called "white spot" in which light leaks from the peripheral portion of the liquid crystal display device and becomes white becomes a problem. 3 201229167 In order to improve the problem of the sample, there is proposed an adhesive which adds a low molecular weight polymer to the adhesive composition to impart stress reduction.

It is composed of a copolymer and a polyfunctional compound. However, in the adhesive composition described in Patent Document 1, since the amount of the low molecular weight acrylic copolymer having a weight average molecular weight of 30,000 or less is large, it is difficult to prevent foaming and peeling under high temperature and high humidity. The method for suppressing leukoplakia is a method of preventing leukoplakia by reducing the stress concentration by following the dimensional change of the polarizing film as in the adhesive composition described in the patent document; and in contrast to this method, An adhesive composition having a cohesive force, which suppresses the area where stress is generated to a minimum, and prevents the generation of white spots.

The following components are obtained: 0.02 to 2 parts by weight of a peroxide; 0 02 to 2 parts by weight of an isocyanate crosslinking agent; and a softening point of 80. (The above-mentioned adhesion imparting resin is 1 to 4 parts by weight. However, Patent Document 2 does not describe the white spot, and if it has only the above configuration, the ability to suppress the generation of white spots is insufficient.
