Abstract
Provided are a liquid crystal composition which has excellent planarity in a case of being formed into a coating film and is also capable of forming a reflective layer having excellent diffuse reflectivity, a reflective layer that is formed using the liquid crystal composition, and a method for producing a reflective layer. Provided also is a copolymer that can be used as an alignment control agent for a liquid crystal compound.
