POLARIZATION FILM LAMINATE PROVIDED WITH ADHESIVE LAYER, AND OPTICAL DISPLAY PANEL IN WHICH POLARIZATION FILM LAMINATE PROVIDED WITH ADHESIVE LAYER IS USED

摘要

Provided is a polarization film laminate, etc., with which it is possible to comprehensively solve the problems of polyenization, decoloration, and heating reddening.　A polarization film laminate comprising a polarization film that includes a polyvinyl-alcohol-based resin, and an adhesive layer provided directly to at least one surface of the polarization film or provided to the at least one surface with an optically transparent polarization-film-protecting film interposed therebetween, the adhesive layer including an adhesive polymer and an ionic compound, the adhesive polymer including 0.1-30 wt.% of polar-group-containing monomers as monomer units among all monomer components constituting the adhesive polymer, and the polarization film laminate having an iodine concentration and a moisture content such that, in an x-y orthogonal coordinate system in which the iodine concentration of the polarization film is represented on the x-axis and the moisture content of the polarization film laminate is represented on the y-axis, the iodine concentration and the moisture content are included within a region bounded by: a first line segment connecting a first coordinate point at an iodine concentration of 7.0 wt.% and a moisture content of 0.7 g/m2, and a second coordinate point at an iodine concentration of 2.2 wt.% and a moisture content of 3.2 g/m2; a second line segment connecting the second coordinate point and a third coordinate point at an iodine concentration of 2.2 wt.% and a moisture content of 4.0 g/m2; a third line segment connecting the third coordinate point and a fourth coordinate point at an iodine concentration of 3.0 wt.% and a moisture content of 4.0 g/m2; a fourth line segment connecting the fourth coordinate point and a fifth coordinate point at an iodine concentration of 10.0 wt.% and a moisture content of 0.7 g/m2; and a fifth line segment connecting the first coordinate point and the fifth coordinate point.
