Claim Text:
1. An elliptical polarization plate having a transparent protective film pasted to one surface of a polarizer and an optically anisotropic film pasted to the other surface, wherein, when measured under condition of incident polarization in the film normal direction from the side of the transparent protective film, the visibility corrected single body transmittance is 43.0% or more, the visibility corrected polarization degree is 95.0% or more, the single body hue value a* is −2.0 to 1.0, the single body hue value b* is −1.0 to 5.0, and the optically anisotropic film satisfies the formulae (1), (2) and (3): wherein Re(450) represents the in-plane phase difference value at a wavelength of 450 nm, Re(550) represents the in-plane phase difference value at a wavelength of 550 nm, and Re(650) represents the in-plane phase difference value at a wavelength of 650 nm.
