Title:
OPTICAL ELEMENT, AND METHOD FOR PRODUCING OPTICAL ELEMENT
Document Type and Number:
WIPO Patent Application WO/2021/020284
Kind Code:
A1
Abstract:
Provided are a method for producing an optical element, and an optical element, the method having high production efficiency, being capable of forming an orientation pattern with high accuracy, being capable of suppressing the production time from being increased even when the size is enlarged, and being capable of orienting a liquid crystal compound appropriately. This method for producing an optical element, which has a liquid crystal layer formed using a liquid crystal composition containing a liquid crystal compound, an orientation film for orienting the liquid crystal compound in the liquid crystal layer, and a support, comprises: an orientation film forming step for forming, on the support, the orientation film having a periodic uneven shape having an inclined surface inclined with respect to the surface of the support; and a liquid crystal layer forming step for forming the liquid crystal layer on the orientation film.
