Abstract

There is provided a polarizing plate with optical compensation layers that is excellent in antireflection characteristic in an oblique direction while maintaining an excellent antireflection characteristic in a front direction, and that has a neutral hue in the oblique direction. A polarizing plate with optical compensation layers according to the present invention is used for an organic EL panel. The polarizing plate with optical compensation layers according to an embodiment of the present invention includes in the following order: a polarizer; a first optical compensation layer; and a second optical compensation layer. The first optical compensation layer shows a refractive index characteristic of nx>nz>ny and has an Re(550) of from 230 nm to 310 nm. The second optical compensation layer shows a refractive index characteristic of nx>nz>ny and satisfies a relationship of Re(450)<Re(550). FIG. 1
