Abstract
A circularly polarizing plate in which tint unevenness in an oblique direction can be suppressed when the circularly polarizing plate is applied to an organic EL display device. The circularly polarizing plate includes a polarizer and a phase difference film laminated on one surface side of the polarizer, in which it has a moisture content of 1.8% or less, an absolute value of a chromaticity a* and chromaticity b* are 10 or less at any azimuthal angle, in a case where the chromaticity a* and b* are measured at all azimuthal angles with a polar angle of 40° from a normal direction of the circularly polarizing plate of a laminate, and when a reflectivity is measured at all azimuthal angles with a polar angle of 40° from the normal direction of the circularly polarizing plate of the laminate, the reflectivity is 3.0% or less at any azimuthal angle.
