Abstract

The invention discloses a positive-negative-mixed liquid crystal composition. The positive-negative-mixed liquid crystal composition is characterized by comprising a component A composed of at least one kind of negative compounds shown in the first general formula (please see the specification for the first general formula) and a component B composed of one or more kinds of positive compounds shown in the second general formula (please see the specification for the second general formula). The liquid crystal composition has the advantages of being positively dielectric, high in charge retention rate, low in rotary viscosity, short in response time and particularly high in transmittance; the positive-negative-mixed liquid crystal composition is suitable for manufacturing a high-transmittance and rapid-responding TFT-LCD.

Description

technical field [0001] The invention belongs to the technical field of liquid crystal materials, and in particular relates to a positive and negative mixed liquid crystal composition and its application in liquid crystal displays. Background technique [0002] Display is the process of converting electrical signals (data information) into visible light (visual information), and the device that completes the display is the Man-Machine Interface (MMI). A flat panel display (Flatpanel Display, FPD) is currently the most popular type of display device. Liquid Crystal Display (LCD) is the first product developed and commercialized in FPD. At present, a thin film transistor liquid crystal display (ThinFilmTransistorLiquidCrystalDisplay, TFT-LCD) has become a mainstream product in LCD applications. [0003] In terms of working principle, LCD is a display device that uses the light emitted by the backlight, through polarizers and liquid crystal cells (liquid crystal molecules), to...
