  • Publication number: 20130337196
    Abstract: The present invention discloses a liquid crystal (LC) molecule having a five-membered ring structure and a mixture thereof. A traditional LC molecule is modified into the LC molecule having the five-membered ring structure. The rotational viscosity of the LC molecule within an LC panel is decreased by properties of the five-membered ring structure, so that the LC molecule having the five-membered ring structure has a fast off-time than that of the traditional LC molecule. The present invention can decrease the rotational viscosity of the LC molecule within the LC panel by modification of the five-membered ring structure of the LC molecule, and thus the problem of cross-talk effect produced from switching a two-dimensional mode to a three-dimensional mode in an LC display can be improved.
