Abstract:
A manufacturing method of a liquid crystal optical element includes preparing a liquid crystal film having a cholesteric liquid crystal, preparing a transparent substrate in which at least a material forming a main surface is an inorganic material, applying a solution containing a silane coupling agent to the main surface of the transparent substrate, stacking the liquid crystal film on the silane coupling agent, and heating the silane coupling agent.
