Abstract

See full text

Provided is a polarizing plate that has an excellent viewing angle characteristic and suppresses changes in display characteristics. A polarizing plate of the present invention is used in an organic EL panel, and includes a polarizer (10), a first retardation layer (30), and a second retardation layer (40). The first retardation layer (30) shows a refractive index characteristic of nx>ny≧nz, satisfies a relationship of Re(450)40) shows a refractive index characteristic of nz>nx≧ny. A laminate of the first retardation layer (30) and the second retardation layer (40) has an Re(550) of from 120 nm to 160 nm and an Rth(550) of from 40 nm to 100 nm.
