摘要：
To provides a transparent protective film, an optical compensation film, a polarizing plate, and a liquid crystal display device in which the variation of Rth in response to variations in humidity of the environment in which they are used is sufficiently small. The protective film in accordance with the present invention is a transparent protective film that satisfies the following Formulas (I) to (III) at a relative humidity of 60% RH; Formula (I): 0≦Re(630)≦10; Formula (II): |Rth(630|≦20; and Formula (III): ΔRth/d×80,000≦20.
