Novel liquid crystal compounds having a tetrahydropyranring structure have been developed. These compounds show large optical anisotropy, large absolute negativedielectricanisotropy and higher solubility with other LC compounds compared with conventional high birefringent negativedielectriccompounds. The two types of tetrahydropyran derivatives have a chair form cyclohexane ring structure with oxygen
