<p>In a process for producing an optical element comprising a light transmitting substrate, an alignment film formed on the substrate and a layer of a liquid crystalline polymer formed on the alignment film, or in a process for producing an optical element, involving transferring a layer of a liquid crystalline polymer formed on an orientating substrate onto a light transmitting substrate, the said liquid crystalline polymer being a heat-polymerizable polymer which exhibits a nematic orientation or a twisted nematic orientation in the state of liquid crystal and which assumes a glassy state at a temperature below the liquid crystal transition point thereof, the liquid crystalline polymer layer is heat-treated at at least one of : during an orientating treatment; or after fixing of the orientation obtained; or, if appropriate, after the transfer.</p> |
