Abstract

The present invention discloses a positive dielectric liquid crystal composition. The liquid crystal composition comprises a component A composed of one or more liquid crystal compounds represented bya general formula I in the description, a component B composed of one or more liquid crystal compounds represented by a general formula II in the description, a component C composed of one or more liquid crystal compounds represented by a general formula III in the description, and an additive component D composed of one or more compounds represented by a general formula S-1 in the description. The composition provided by the present invention does not change under the conditions of high temperature and ultraviolet radiation, thereby improving the quality of liquid crystals; and the composition is applicable to active matrix electro-optical elements and liquid crystal displays, and can be used for TFT-LCD used under civil and special harsh conditions.

Description

technical field [0001] The invention relates to the field of liquid crystal materials, in particular to a positive dielectric 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) Stable chemical and physical properties; [0004] (2) Low viscosity; [0005] (3) have a suitable △ε; [0006] (4) Appropriate demolition rate △n; [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...
