Liquid crystal composition, liquid crystal alignment mixture and liquid crystal display device |
摘要 |
The present invention discloses a liquid crystal composition, a liquid crystal mixture and a liquid crystal panel. The liquid crystal composition comprises one or more types of first liquid crystal molecules substituted by difluoroalkenyl group and one or more types of second liquid crystal molecules for vertical alignment. The probability of polymerization between polymerizable monomers and the first liquid crystal molecules can be effectively reduced by the steric effect caused by the difluoroalkenyl group of the first liquid crystal molecules during a process of polymer alignment. Thus, the probability of polymerization occurred between the polymerizable monomers and polyimide on the surface of an alignment film is increased, so as to solve the problem of the image sticking. |

1. A liquid crystal alignment mixture for a polymer alignment process, distributing liquid crystal molecules onto a surface of an alignment film, and comprising:
a liquid crystal material consisting of at least one first liquid crystal molecule with difluoroalkenyl group and at least one second liquid crystal molecule for vertical alignment; and a polymerizable monomer; wherein the first liquid crystal molecule has the following formula (I): the A group represents at least one six-membered ring, R represents n-propyl group, and n=1 or 2; the second liquid crystal molecule has the following (II); the B group represents at least one six-membered ring; and wherein the weight ratio of the first liquid crystal molecule is 0.1-20%, the weight ratio of the second liquid crystal molecule is 80-99.0%, and the weight ratio of the polymerizable monomer is 0.015-0.5%. |
