Claim 1:
2. An optical film comprising at least:
an optically anisotropic layer; and
a polarizer,
wherein the optically anisotropic layer is optically uniaxially anisotropic, while in a case where an optic axis of the optically anisotropic layer is projected onto the polarizer as viewed from an optically anisotropic layer side, an angle formed by the optic axis and an absorption axis of the polarizer is +50° to +70° or −50° to −70°,
an average tilt angle of the optic axis with respect to a main surface of the optically anisotropic layer is 20° to 45°, and
an in-plane phase difference Re (550) of the optically anisotropic layer at a wavelength of 550 nm is 70 nm to 240 nm.
