Abstract

The invention discloses a liquid crystal composition and application thereof. The liquid crystal composition comprises a component A and a component B. The liquid crystal composition has appropriate optical anisotropy, is very high in charge retention rate, rapid in response, low in rotation viscosity and short in response time, and can retain a high charge retention rate, low power consumption and the like. Within the range of the composition disclosed by the invention, the contents of different components can be adjusted so as to expand liquid crystal compositions with characteristics of different thresholds, bright points and birefringence. The liquid crystal composition disclosed by the invention has a wide application prospect and a high application value in liquid crystal display, and is particularly applicable to manufacturing of active matrix TN-TFT and IPS-TFT displays with rapid response.

Description

technical field [0001] The present invention relates to liquid crystal mixtures and liquid crystal displays comprising these liquid crystal mixtures, in particular to displays addressed by an active matrix, and to TN mode and IPS mode in this driving mode. It also relates to displays driven by other known means. technical background [0002] Liquid crystal display elements are divided into the following modes according to the display mode: twisted nematic (TN) mode, super twisted nematic (STN) mode, in-plane mode (IPS), and vertical alignment (VA) mode. Regardless of the display mode, the liquid crystal composition needs to have the following characteristics. [0003] (1) Chemical and physical properties are stable. [0004] (2) Low viscosity. [0005] (3) Have a suitable Δε. [0006] (4) Appropriate demolition rate Δn. [0007] (5) Good compatibility with other liquid crystal compounds [0008] As a liquid crystal material, it is required to have good chemical and the...
