An optical film in which heat resistance or moisture resistance is excellent, and visibility is able to be sufficiently ensured. In the optical film used in a display apparatus including a polarizer, Re is 1,000 nm to 30,000 nm, and Rth is −30,000 nm to −1,000 nm. Further, a polarization plate including the optical film, a transparent conductive film including the optical film, a surface protection film including the optical film including the optical film, and a liquid crystal display apparatus including the optical film.
