Abstract
The present invention provides a liquid crystal composition having easily adjustable rotational viscosity while maintaining stability at low temperature, a clearing point and dielectric anisotropy (positive value) in an optimal condition according to an exemplary embodiment of the present invention, including: at least one liquid crystal compound selected from the group consisting of liquid crystal compounds represented by the following Chemical Formula 1, as a first component; at least one liquid crystal compound selected from the group consisting of liquid crystal compounds represented by the following Chemical Formula 2, as a second component; and at least one liquid crystal compound selected from the group consisting of liquid crystal compounds represented by the following Chemical Formula 3, as a third component. The liquid crystal composition according to the present invention has high clearing point and refractive index anisotropy, a controllable modulus of elasticity, and high specific resistance, and the rotational viscosity thereof is easily adjustable to be low. Thus, the liquid crystal composition satisfying various liquid crystal display (LCD) device characteristics is provided.
