Abstract:
A method for producing an optical element, the method comprising the steps of: forming a liquid crystal polymer layer on a sheet-form substrate; forming a surface protective layer on the liquid crystal polymer layer; and carrying out a heat-treatment for crosslinking the liquid crystal polymer, or the method comprising the steps of: forming a liquid crystal polymer layer on a sheet-form substrate; carrying out a first heat-treatment for controlling the multidomain structure of the liquid crystal polymer layer; forming a surface protective layer on the liquid crystal polymer layer; and carrying out a second heat-treatment for crosslinking the liquid crystal polymer layer.
