1. A method of manufacturing an optical element, the optical element including an optically-anisotropic layer that is formed using a liquid crystal composition including a liquid crystal compound, an alignment film that aligns the liquid crystal compound, and a support, the method comprising:
an alignment film forming step of forming the alignment film on one surface of the support; and
an optically-anisotropic layer forming step of forming the optically-anisotropic layer on the alignment film,
wherein the alignment film includes a photo-alignable material,
the alignment film forming step includes an exposure step of exposing different in-plane positions of the alignment film to light components having different polarization directions, and
the support includes a reflection suppressing portion that suppresses reflection of light in a wavelength range of at least a part of a light absorption band where a photochemical reaction occurs in the alignment film by irradiating a surface opposite to a surface where the alignment film is formed with the polarized light in the exposure step.
