Title:
POLARIZING FILM LAMINATE, OPTICAL DISPLAY PANEL IN WHICH SAID POLARIZING FILM LAMINATE IS USED, POLARIZING FILM LAMINATE WITH TRANSPARENT ADHESIVE LAYER, AND POLARIZING FILM ASSEMBLY
Document Type and Number:
WIPO Patent Application WO/2021/039987
Kind Code:
A1
Abstract:
Provided are, inter alia, a polarizing film laminate in which the effect of solar irradiation is suppressed, whereby the problems of polyene formation, color loss, and heat-induced reddening can be comprehensively overcome. In an orthogonal coordinate system having the iodine concentration (wt%) of a polarizing membrane along the x-axis and the moisture content (g/m2) of the polarizing film laminate along the y-axis, the iodine concentration and moisture content are contained within the region surrounded by a first line segment connecting a first coordinate point (x: 6.0, y: 0.7) and a second coordinate point (x: 1.8, y: 4.2), a second line segment connecting the second coordinate point and a third coordinate point (x: 1.8, y: 5.1), a third line segment connecting the third coordinate point and a fourth coordinate point (x: 5.7, y: 2.6), a fourth line segment connecting the fourth coordinate point and a fifth coordinate point (x: 7.0, y: 0.7), and a fifth line segment connecting the first coordinate point and the fifth coordinate point. In the present invention, a polarizing-membrane protective film is a light-absorbing layer having a light-absorption function, the film transmitting no more than 5% of light having a wavelength of 380 nm.
