Method for producing optical element, and optical element |
| abstract |
The present invention provides: a method for producing an optical element, which is capable of forming an optically anisotropic layer that is suppressed in in-plane unevenness; and an optical element. A method for producing an optical element that comprises an optically anisotropic layer which is formed with use of a liquid crystal composition containing a liquid crystal compound, an alignment film which aligns the liquid crystal compound, and a supporting body. This method for producing an optical element comprises: an alignment film formation step wherein an alignment film is formed on one surface of a supporting body; and an optically anisotropic layer formation step wherein an optically anisotropic layer is formed on the alignment film. The alignment film contains a photo-alignment material; and the alignment film formation step comprises a light exposure step wherein different in-plane positions of the alignment film are exposed to light having different polarization directions. The supporting body scatters light in at least a part of the wavelength range of the light absorption band, where a photochemical reaction of the alignment film occurs, by means of irradiation of light that is polarized during the light exposure step. |
