(57) [Summary] The pressure-sensitive adhesive sheet 1A of the present invention is used by being adhered to a liquid crystal cell. The pressure-sensitive adhesive layer 3 is bonded to one side of a base layer 2 constituting a polarizing plate. Further, the base material layer 2 of the pressure-sensitive adhesive layer 3 The release sheet 4 is adhered to the surface on the side opposite to the above. The pressure-sensitive adhesive layer 3 is composed of a laminate in which layers 31 and 32 are laminated. As the adhesive constituting each of the layers 31 and 32, for example, an adhesive mainly containing an acrylic adhesive is used. Due to differences in the degree of crosslinking, the amount of plasticizer added, and the like in the two layers 31 and 32, the shear elastic modulus and the relaxation elastic modulus of the layer 32 are lower than those of the layer 31. [Effect] The stress caused by shrinkage of the base material layer can be reduced, and the stress concentration can be reduced. In particular, white spots and color unevenness of the liquid crystal cell can be suppressed. |
