Abstract

The invention provides a negative liquid crystal composition comprising: at least one compound represented by the general formula I and used as a first ingredient; at least one compound represented by the general formula II and used as a second ingredient; and a 1-2000 ppm antistatic agent comprising at least one crown ether compound and a compound represented by the formula V. The negative liquid crystal composition can effectively reduce the current power consumption, reduce the electrostatic discharge time, and greatly reduce risks of generation of image ghost shadow, image display unevenness and other display poor problems. The invention also provides a liquid crystal display comprising the negative liquid crystal composition.
