An optical film, a polarizing plate and an LC(Liquid Crystal) panel are provided to prevent generation of light leakage and color shift and supply wide viewing angle. An optical film is made from thermoplastic norbornene resin. At light wave 590nm, the maximum reflective index in a film surface is nx. A reflective index of a direction orthogonal to the nx in the film surface is ny. A reflective index of a film thickness direction is nz. A film thickness is d(nm). A phase difference of the film thickness direction Rth(590)[nm]={(nx+ny)/2-nz}xd belongs to a range between 10nm and 30nm.
