Abstract

The invention discloses a liquid crystal composition and a liquid crystal display, belonging to the technical field of liquid crystal displays. The liquid crystal composition contains at least one compound represented by general formula I, and one or more compounds selected from general formula IIA, IIB or IIC. The liquid crystal composition of the invention has good low-temperature mutual solubility, large elastic constant, and can shorten response time.

Description

technical field [0001] The invention relates to the technical field of liquid crystal materials, in particular to a negative liquid crystal composition and a liquid crystal display. Background technique [0002] Liquid crystal display devices are used in various home appliances including clocks and calculators, measuring equipment, automotive panels, word processors, electronic notebooks, printers, computers, and televisions. As liquid crystal display methods, the representative methods are TN (twisted nematic) type, STN (super twisted nematic) type, DS (dynamic light scattering) type, GH (guest-host) type, IPS (in-plane switching) type, OCB (Optical Compensated Birefringence) type, ECB (Voltage Controlled Birefringence) type, VA (Vertical Alignment) type, CSH (Color Super Vertical) type and FLC (Ferroelectric Liquid Crystal) type, etc. Also, examples of driving methods for liquid crystal displays include static driving, multiplex driving, simple matrix methods, and active ...
