Abstract

The present invention provides an optically anisotropic layer which has a plurality of regions in which alignment states of a liquid crystal compound are different in a thickness direction and in which peeling is unlikely to occur in the layer. The optically anisotropic layer of the present invention is an optically anisotropic layer formed of a liquid crystal compound, in which the optically anisotropic layer contains a leveling agent and satisfies a predetermined requirement in a profile of a secondary ion intensity derived from the leveling agent in a depth direction, which is obtained by analyzing components of the optically anisotropic layer in a depth direction by time-of-flight secondary ion mass spectrometry while irradiating the optically anisotropic layer with an ion beam from one surface of the optically anisotropic layer to the other surface of the optically anisotropic layer.
