Abstract
A process for producing a highly uniaxially oriented film is disclosed, comprising supporting a composition comprising two or more liquid crystal monomers displaying a nematic or smectic state and having a polymerizable functional group in the molecule thereof and a photopolymerization initiator on or between a support or supports having been subjected to orientation, and irradiating said composition with radiation while maintaining said composition in a liquid crystal state to cause polymerization of said composition. The resulting film is free from pinholes, strain or unevenness and is excellent in optical transparency.
