ABSTRACT:
A cellulose acylate film that has: an in-plane retardation Re and a retardation Rth in a thickness direction at a wavelength of 590 nm, which are satisfied with ranges of expressions (I) to (III); a coefficient of a thermal expansion of from 20 ppm/° C. to 100 ppm/° C.; and a haze of from 0.01 to 0.8, and a polarizing plate and a display device using the same.in-line-formulae description="In-line Formulae" end="lead"?20≦Re≦50  Expression (I)in-line-formulae description="In-line Formulae" end="tail"?in-line-formulae description="In-line Formulae" end="lead"?70≦Rth≦200  Expression (II)in-line-formulae description="In-line Formulae" end="tail"?in-line-formulae description="In-line Formulae" end="lead"?1.0≦Rth/Re≦3.0  Expression (III)in-line-formulae description="In-line Formulae" end="tail"?In the foregoing expressions, each of Re and Rth is a value at 25° C. and 60% RH, and has a unit of nm.
