POLARIZING FILM LAMINATE HAVING TRANSPARENT ADHESIVE LAYER, AND DISPLAY PANEL

WIPO Patent Application WO/2017/014242

A1

Provided is an easily and inexpensively producible polarizing film laminate containing an adhesive layer and capable of effectively suppressing internal reflection when used in an image display panel. By forming a refractive index-adjusting section that has a higher refractive index than does the base material of the adhesive layer, throughout a given range in the thickness direction from the surface of the adhesive layer, it is possible, when using the adhesive layer to join optical members, to suppress internal reflection in a laminate formed from the optical members. A polarizing film laminate comprising an adhesive layer and a polarizing film on a principal surface of the adhesive layer, and containing a base adhesive section substantially formed from a transparent adhesive base material starting from one principal surface and extending in the thickness direction, and a transparent, adhesive refractive index-adjusting section formed from the other principal surface of the adhesive layer and extending in the thickness direction, wherein the refractive index-adjusting section has a higher refractive index than does the refractive index of the adhesive base material, and the adhesive base material section of the adhesive layer is positioned on the polarizing film-side of the adhesive layer.
