Title:
LIQUID CRYSTAL ELEMENT AND METHOD FOR PRODUCING SAME
Document Type and Number:
WIPO Patent Application WO/2021/235088
Kind Code:
A1
Abstract:
This liquid crystal element 10 is provided with: a first base material 11 that is provided with a first electrode; a second base material 12 that is provided with a second electrode, while being arranged so as to face the first base material 11; and a liquid crystal layer 13 that is formed by curing a liquid crystal composition containing a liquid crystal and a polymerizable compound, while being arranged so as to be adjacent to the first base material 11 and the second base material 12. With respect to this liquid crystal element 10, if the liquid crystal layer 13 is removed from at least one of the first base material 11 and the second base material 12, and the base material from which the liquid crystal layer 13 has been removed, is immersed in hexane at 23°C for 30 seconds and is subsequently dried, the base material surface on the side from which the liquid crystal layer has been removed has a silicon atom ratio of from 0.05% to 10% relative to the total amount of carbon atoms, oxygen atoms and silicon atoms as determined by X-ray photoelectron spectroscopy.
