Abstract

The invention discloses a positive liquid crystal composition, which is characterized in that the composition, as a component A, contains one or more compounds as shown in general formula I, and as a compound B, contains one or more compounds as shown in general formula II-1 and / or II-2. The liquid crystal composition disclosed by the invention has rapid response, moderate optical anisotropy, good stability to light and heat, and is particularly suitable for improving the permeability of IPS (in-plane switching), FFS (fringe-field switching) or other modes of liquid crystal display devices.

Description

Technical field [0001] The invention belongs to the technical field of liquid crystal materials, and specifically relates to a positive liquid crystal composition and its application in a liquid crystal display. Background technique [0002] Display is the process of transforming data information that uses electrical signals as the transmission medium into visual information that uses visible light as the transmission medium. The device that completes the display is the Man-Machine Interface, MMI. Flatpanel Display, FPD is currently the most popular type of display device. Liquid CrystalDisplay, LCD is the first product developed and commercialized in FPD. At present, Thin Film Transistor Liquid Crystal Display and TFT-LCD have become mainstream products in LCD applications. [0003] In terms of working principle, the display device of LCD is to use the light emitted by the backlight source, through the polarizer and liquid crystal cell liquid crystal molecules, etc., to produce ...
