Abstract: Provided are an optical film, a circularly polarizing plate, and an image display apparatus in each of which the occurrence of cracks is suppressed in the obtained film in a case of being punched. The optical film includes a stretched resin film and a liquid crystal layer formed by fixing a liquid crystal compound twist-aligned along a helical axis extending along a direction in thickness, in which a δa value calculated using a three-dimensional solubility parameter of a resin in the stretched resin film is 8.0 MPa1/2 or less, the liquid crystal layer contains a cured substance of a polyfunctional compound having two or more polymerizable groups in one molecule, and an absolute value of a difference between the δa value calculated using the three-dimensional solubility parameter of the polyfunctional compound and the δa value calculated using the three-dimensional solubility parameter of the resin is 4.0 MPa1/2 or less.
