Abstract: An optical film suppresses at any azimuthal angle where the optical film is combined with a polarizer and applied as a circularly polarizing plate to a display device; a circularly polarizing plate; and a display device. The optical film includes a first, a second, and a third optically anisotropic layer in this order, in which the first layer is formed by fixing a vertically aligned disk-like liquid crystal compound or formed by fixing a horizontally aligned rod-like liquid crystal compound, the second layer is formed by fixing a rod-like liquid crystal compound twist-aligned along a helical axis extending in a thickness direction, the third layer is formed by fixing a vertically aligned rod-like liquid crystal compound, and at least one of the first, second, or third layers is formed of a liquid crystal compound containing a reverse wavelength dispersion liquid crystal compound.
