Abstract
A method for producing a cholesteric liquid crystal layer is a method that can produce a cholesteric liquid crystal layer whose reflection surface is not parallel to a substrate surface by a simple method. The method includes: a step 1 of forming a composition layer satisfying a condition 1, a condition 2, or a condition 3 on a substrate, using a liquid crystal composition including a liquid crystal compound; and a step 2 of subjecting the composition layer to a treatment for cholesterically aligning the liquid crystal compound in the composition layer to form a cholesteric liquid crystal layer.
