Patent ID: 8711300

Claim:
A process for producing a liquid crystal element comprising an alignment-treated substrate and a layer of polymer liquid crystal having a pattern, which comprises: a step of forming a layer of cross-linkable polymer liquid crystal on the alignment-treated substrate, a step of aligning mesogenic groups in the cross-linkable polymer liquid crystal, a step of pressing a mold having a reverse pattern of a pattern to be imparted to the layer of polymer liquid crystal, against the layer of cross-linkable polymer liquid crystal, at a temperature higher than the glass transition temperature of the cross-linkable polymer liquid crystal and lower than the clearing point temperature of the cross-linkable polymer liquid crystal, a step of cross-linking the cross-linkable polymer liquid crystal while the mold is pressed against the layer of cross-linkable polymer liquid crystal, to form a cured product, and a step of removing the mold from the cured product.
