Title: OPTICAL COMPENSATION LAYER-EQUIPPED POLARIZING PLATE AND ORGANIC EL PANEL USING SAME
Abstract:
Provided is an optical compensation layer-equipped polarizing plate which exhibits an excellent reflective color phase and excellent viewing angle characteristics. This optical compensation layer-equipped polarizing plate is to be used in an organic EL panel, and is equipped with a polarizer, a first optical compensation layer, and a second optical compensation layer, in this order. The first optical compensation layer exhibits refractive index properties satisfying nz>nx>ny, the Re(550) thereof is 5-150nm, and the Rth(550) thereof is -240 to -20nm. The second optical compensation layer exhibits refractive index properties satisfying nx>ny≥nz, the Re(550) thereof is 100-180nm, the Nz coefficient is 1.0-2.0, and the relationship Re(450)
