Provided is an optical film with a resin substrate adhered to an optically anisotropic layer and suppression of occurrence of optical defects in the optically anisotropic layer. The optical film has a resin substrate having an alignment regulating force and an optically anisotropic layer arranged thereon, in which the optically anisotropic layer contains a liquid crystal compound and a compound having a heteroatom different from the liquid crystal compound, and in a case where a surface of the optical film on an optically anisotropic layer side thereof is a first surface and a surface of the optical film on a resin substrate side thereof is a second surface, and components of the optical film in a depth direction are analyzed by time-of-flight secondary ion mass spectrometry while irradiating the optical film with an ion beam from the first surface toward the second surface, the obtained profile satisfies a predetermined requirement.

Optical film

The present invention provides a light absorption anisotropic film excellent in adhesiveness to an adjacent layer, and a laminate and an image display device, in which the light absorption anisotropic film is used. The light absorption anisotropic film is formed from a liquid crystal composition that contains a high-molecular weight liquid crystal compound and a dichroic substance, and is a light absorption anisotropic film in which regarding a signal derived from the dichroic substance detected by a time-of-flight secondary ion mass spectrometry, a relationship between a maximum intensity Imax in a thickness direction of a film and an intensity Isur on at least one surface of the film satisfies Expression (I-1) 2&#x2264;Imax/Isur.
