Abstract

The invention provides a liquid crystal display device. The liquid crystal display device includes an upper substrate, a liquid crystal material layer, and a lower substrate, wherein the liquid crystal material layer is composed of a liquid crystal composition, and the liquid crystal composition comprises one or more compounds of a formula I. The liquid crystal display device including the liquidcrystal composition has the advantages of low driving voltage, high voltage retention rate, fast response speed, high contrast ratio, and good low-temperature storage characteristic.

Description

technical field [0001] The invention relates to the field of liquid crystal display, in particular to a liquid crystal display device with the characteristics of good low-temperature storage stability, high contrast, fast response, low driving voltage, high voltage retention rate and the like. Background technique [0002] In liquid crystal display elements, the classification based on the operation mode of liquid crystal molecules is: phase change (phase change, PC), twisted nematic (twisted nematic, TN), super twisted nematic (super twisted nematic, STN), electrically controlled birefringence (electrically controlled birefringence, ECB), optically compensated bend (optically compensated bend, OCB), in-plane switching (IPS), vertical alignment (vertical alignment, VA), fringe field switching (fringe field switching, FFS), electric field Field-induced photo-reactive alignment (FPA) and other modes. The classification of component-based driving methods is: passive matrix (pa...
