Abstract: Provided is a method for producing a reflective layer having excellent diffuse reflectivity. The method for producing a reflective layer of the present invention includes Step 1 of applying a composition containing a liquid crystal compound and a chiral agent onto a substrate and heating the applied composition to align the liquid crystal compound into a cholesteric liquid crystalline phase state, and Step 2 of forming a reflective layer by cooling or heating the composition so that the helical twisting power of the chiral agent contained in the composition in the cholesteric liquid crystalline phase state increases by 5% or more.
