Title:
POLARIZING PLATE WITH OPTICAL COMPENSATION LAYER AND ORGANIC EL PANEL USING SAME
Document Type and Number:
WIPO Patent Application WO/2017/169168
Kind Code:
A1
Abstract:
Provided is a polarizing plate with an optical compensation layer, which has excellent antireflection characteristics in an oblique direction, while maintaining excellent antireflection characteristics in the front direction, and which enables the achievement of such excellent antireflection characteristics over a wide wavelength band, while having a neutral hue in the oblique direction. A polarizing plate with an optical compensation layer according to the present invention is used in an organic EL panel. This polarizing plate with an optical compensation layer is provided with a polarizer, a first optical compensation layer, a second optical compensation layer and a third optical compensation layer. The first optical compensation layer, the second optical compensation layer and the third optical compensation layer have refractive index characteristics satisfying nx > nz > ny, while satisfying the relational expression Re(450) ≥ Re(550) in one embodiment of the present invention.
