POLARIZATION PLATE AND DISPLAY DEVICE USING POLARIZATION PLATE

WIPO Patent Application WO/2019/216120

A1

This polarization plate has: a hard coat layer on one surface; and an adhesive layer on the other surface. A polarizer of the polarization plate includes at least one dichroic dye. The polarization plate has a single-film transmittance Ys of 45-60% and a polarization degree Py of 50-95%, which are obtained through measurement of light in a wavelength range of 380-780 nm and then visibility correction thereof. The polarization plate has a*s of not less than -3 but not more than +3 and b*s of not less than -3 but not more than +3 in the hue of an L*a*b* color system, and has a*p of not less than -3 but not more than +3 and b*p of not less than -3 but not more than +3 in the hue when two polarizing films are used so that the polarization axes thereof are positioned in parallel.
