Title: POLARIZING PLATE WITH OPTICAL COMPENSATION LAYER, AND ORGANIC EL PANEL USING SAID POLARIZING PLATE
Abstract:
Provided is a polarizing plate with an optical compensation layer, said polarizing plate having excellent antireflection characteristics in the oblique direction while maintaining excellent antireflection characteristics in the frontal direction, wherein the hue in the oblique direction is neutral. The polarizing plate with an optical compensation layer is used in an organic EL panel. The polarizing plate with an optical compensation layer comprises, in the following order, a polarizer, a first optical compensation layer, and a second optical compensation layer. The first optical compensation layer exhibits refractive index characteristics of nx>nz>ny and has a Re(550) of 230nm-310nm. The second optical compensation layer exhibits refractive index characteristics of nx>nz>ny and satisfies the relation Re(450)
