Abstract
In a process for producing a liquid crystal element comprising an alignment-treated substrate and a layer of polymer liquid crystal having a pattern, mesogenic groups in cross-linkable polymer liquid crystal are aligned, and the cross-linkable polymer liquid crystal is cross-linked while the mold is pressed 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.
