Abstract
Provided is a polarizing film laminate comprising: an element substrate; a polarizer; a transparent electroconductive layer patterned so as to function as a touch sensor; and a pressure-sensitive adhesive layer, 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 the adhesive layer in a thickness direction of the adhesive layer; and a refractive index adjustment zone formed over a given range from the adhesive layer in the thickness direction and comprising the base adhesive material and material infiltrated into the base adhesive material and different from the base adhesive material, the refractive index adjustment zone having an average refractive index greater than a refractive index of the base adhesive material, and wherein the base adhesive material zone of the adhesive layer is located on the side of the element substrate.
