摘要:
Provided is a polarizing film laminate comprising a pressure-sensitive adhesive layer, and a polarizing film wherein the adhesive layer comprises: a base adhesive zone made of a transparent base pressure-sensitive adhesive material and formed over a given range from one principal surface of the adhesive layer in a thickness direction of the adhesive layer; and a refractive index adjustment zone formed over a given range from the other principal surface of the adhesive layer in the thickness direction and comprising the base pressure-sensitive adhesive material and material infiltrated into the base pressure-sensitive adhesive material and different from the base pressure-sensitive adhesive material, the refractive index adjustment zone having an average refractive index greater than a refractive index of the base pressure-sensitive adhesive material, and wherein the base pressure-sensitive adhesive material zone of the pressure-sensitive adhesive layer is located on the side of the polarizing film.
