If the weight average molecular weight is less than about i〇〇〇〇〇g/m〇l, the resulting heat resistance is insufficient. If the weight average molecular weight exceeds about 2,000,000, the resulting adhesion is low and the viscosity is lowered. Herein, the weight average molecular weight is based on the polystyrene standard determined by the method described in the following examples. It should be noted that the total amount of the monomer (al) and the monomer (a2) is not 0 parts by weight.

Based on about 100 parts by weight of the composition (A), The amount of the oxide crosslinking agent (B) may be from about 0.01 to about 5 parts by weight, preferably from about 1 to about 8 parts by weight. Within this range, a suitable crosslinked structure can be formed to achieve excellent heat resistance. If the amount of the peroxide crosslinking agent (B) is less than about 1 part by weight, it does not open into a sufficiently crosslinked structure, thereby lowering heat resistance. If the amount of the peroxide crosslinking agent (B) exceeds About 5 parts by weight, the crosslinking reaction proceeds excessively until the viscosity is lowered, whereby the shrinkage of the polarizer plate with time cannot be treated, thereby reducing light leakage resistance and durability. Component (B) can be used alone or as both of them.

Within this range, a suitable crosslinked structure can be formed to achieve excellent heat resistance. Further, the component (C) can promote the crosslinking effect of the peroxide crosslinking agent. Therefore, the adhesive composition according to this embodiment exhibits practical adhesive properties shortly after the bonding treatment (within 10 minutes after the bonding treatment), thereby sufficiently improving the productivity. If the amount of the carbodiimide crosslinking agent (C) is less than about 0.001 part by weight, a sufficiently crosslinked structure is not formed, thereby lowering heat resistance. Moreover, the carbodiimide crosslinker does not promote the crosslinking effect of the peroxide crosslinker and requires a specific aging time until the adhesive composition achieves a practical adhesive property. If the amount of the carbodiimide cross-linking agent (C) exceeds about 5 parts by weight, the crosslinking reaction proceeds excessively, thereby lowering the viscosity, so that the adhesive composition cannot cope with the shrinkage of the polarizer plate over time, thereby reducing the resistance. Light leakage and durability. (D) Isocyanate crosslinking agent In addition to the components (A), (B) and (C), the binder composition may further comprise an isocyanate crosslinking agent (hereinafter also referred to as "component (D)").
