Document Type and Number:
WIPO Patent Application WO/2023/274417
Kind Code:
A1
Abstract:
The present application relates to a liquid crystal composition, and a preparation method therefor and the use thereof. The liquid crystal composition of the present invention comprises: one or more compounds as shown in formula (1), wherein n in formula (1) is equal to 3, 4, 5 or 7; one or more compounds as shown in formula (2), wherein n in formula (2) is more than or equal to 2; and one or more compounds as shown in formula (3), wherein n in formula (3) is more than or equal to 3. The liquid crystal composition of the present invention has a high refractive index and has both a high clearing point and a low crystallization point.
