Process for producing optical element, optical element, optical films using optical element, and illuminator and liquid crystal display each using optical element or optical films |
摘要 |
A process for producing an optical element which comprises a polymeric liquid crystal layer having a helically twisted molecular structure and has satisfactory thickness precision and satisfactory optical properties. The process comprises applying a mixed solution containing a polymerizable nematic liquid crystal compound and a polymerizable chiral reagent to an oriented substrate, followed by drying, to orient the liquid crystal compound; and irradiating the mixed solution applied with radiation from the oriented substrate side while maintaining the mixed solution in contact with a gas comprising oxygen to thereby polymerize and cure the mixed solution.
