Abstract: A phase difference film and a circularly polarizing film each achieve suppressed coloration when viewed from the front direction, a smaller difference in tint between views from the front direction and the oblique direction, and suppressed image unevenness, where the film is applied to an image display panel, in particular, an organic EL panel; as well as an image display device including the circularly polarizing film. The phase difference film includes optically anisotropic layers A and B, in which a retardation RthA of layer A in the thickness direction at a wavelength of 550 nm is larger than 0, layer A exhibits predetermined optical properties, a retardation RthB of layer B in the thickness direction at a wavelength of 550 nm is smaller than 0, layer B satisfies predetermined optical properties, and the angle formed between a slow axis of the optically anisotropic layers A and B is 90°±10°.
