Abstract

There is provided a polarizing plate with optical compensation layers having the following features: the polarizing plate is excellent in antireflection characteristic in an oblique direction while maintaining an excellent antireflection characteristic in a front direction; the polarizing plate can achieve such excellent antireflection characteristics over a wide wavelength band; and the polarizing plate 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 includes: a polarizer; a first optical compensation layer; a second optical compensation layer; a third optical compensation layer; and a fourth optical compensation layer. Each of the first optical compensation layer, the second optical compensation layer, the third optical compensation layer, and the fourth optical compensation layer shows a refractive index characteristic of nx>nz>ny.
