Abstract
Provided is a method for producing an optically anisotropic layer, with a polarizer, which has a plurality of regions in which alignment states of a liquid crystal compound are fixed and different from one another; laminate, with a polarizer; and a composition. The method includes: 1) forming a composition layer containing a chiral agent containing at least a photosensitive chiral agent and a polymerizable liquid crystal compound on a substrate, 2) subjecting the composition layer to a heat treatment, 3) subjecting the composition layer to light irradiation under oxygen concentration of 1% by volume or more, after step 2), and 4) subjecting the composition layer to a curing treatment to form an optically anisotropic layer, and 5) carrying out step 3) under heating conditions, or subjecting the composition layer to a heat treatment between step 3) and step 4), with a predetermined amount of chiral agent.
