Polarizing film stack, optical display panel used with polarizing film laminate, polarizing film stack with transparent adhesive layer, and polarizing film assembly

摘要

Problem to be solved: to provide a polarizing film laminate or the like capable of comprehensively solving the problem of polyenization, color fading and heating red change by suppressing the effect of sunlight irradiation.X axisIn an orthogonal coordinate system in which the y-axis is the water content (g / m2) of the polarization film stackX - Y coordinate points(6.0The first coordinate point of 0.7 and(1.8A first line segment that connects the second coordinate point ofThe second coordinate point(1.8The second line connecting the third coordinate point of 5.1.The third coordinate point(5.7The third line that connects the fourth coordinate point of 2.6.The fourth coordinate point and(7.0The fourth line that connects the fifth coordinate point of 0.7It has iodine concentration and water content contained in the region surrounded by the fifth line segment connecting the first and second coordinate points and the fifth coordinate pointFilm protection filmA light absorbing layer having an optical absorption function;The transmittance of light at 380 nm is 5% or less.Diagram
