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.

A method for producing an optical element, said method comprising the steps of:
- forming a liquid crystal polymer layer on a sheet-form substrate;
- forming a surface protective layer on said liquid crystal polymer layer;
- and thereafter
- carrying out a heat-treatment for crosslinking said liquid crystal polymer at a temperature not higher than 80.degree. C. and not higher than the liquid phase-isotropic phase phase-transition temperature of a liquid crystal polymer constituting said liquid crystal polymer layer, wherein said sheet-form substrate is wound in a roll form.
A method for producing an optical element, said method comprising the steps of:
