Abstract

The invention discloses a positive dielectric liquid crystal composition. The positive dielectric liquid crystal composition comprises a component A which consists of one or more liquid crystal compounds shown in a general formula I, and an additive component D which consists of one or more compounds shown in a general formula S-1, a structural formula S-2, a structural formula S-3 and a general formula S-4. The positive dielectric liquid crystal composition does not change under the conditions of high temperature and ultraviolet radiation, so that the liquid crystal quality is improved; the positive dielectric liquid crystal composition is applicable to an active matrix electric optical element and a liquid crystal display, and can be applied to civil use and practical TFT-LCDs (Thin-Film Transistor Liquid Crystal Displays) under special severe conditions.

Description

technical field [0001] The invention relates to the field of liquid crystal materials, in particular to a positive liquid crystal composition. Background technique [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] With the maturity of TFT technology in the early 1990s, color liquid crystal flat panel displays developed rapidly. In less than 10 years, TFT-LCD has rapidly grown into a mainstream display, which is inseparable from its advantages. Its advanta...
