Abstract

The application discloses a liquid crystal composition and application thereof in liquid crystal display. The liquid crystal composition comprises compounds shown in formula I, II, III and IV. The liquid crystal composition has excellent performance, wide nematic phase temperature range, proper positive dielectric anisotropy, proper optical anisotropy, high charge retention rate, quick response, low rotary viscosity and wide application prospect and application value in liquid crystal display. By utilizing the liquid crystal composition, high charge retention rate, low power consumption and quick response time can be maintained. The liquid crystal composition is especially suitable for manufacturing active matrix EN-TFT and IPS-TFT displayers with quick response. The expression formula is as shown in the description.

Description

technical field [0001] The invention relates to a positive dielectric liquid crystal composition, which has the characteristics of high charge retention rate, low power consumption, low rotational viscosity, appropriate response time, and stable high and low temperature performance, and is suitable for small-sized active matrix electro-optical elements and liquid crystals in the monitor. 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 [000...
