Liquid crystal composition and application thereof

Abstract

The invention belongs to the technical field of liquid crystal display, and discloses a liquid crystal composition. The liquid crystal composition comprises a compound shown in a formula I and a compound shown in a formula II. The liquid crystal composition has a high clearing point, a large K value, good low-temperature intersolubility and good reliability. The residual image of the liquid crystal composition can be effectively improved. The invention also discloses a liquid crystal display element or a liquid crystal display comprising the liquid crystal composition.

Description

technical field [0001] The invention belongs to the technical field of liquid crystal display. More specifically, it relates to a liquid crystal composition and its application. Background technique [0002] With the development of science and technology, the electronicization of medical devices continues to deepen, which makes the display screens required for medical devices to be further developed. If the existing display screens of ordinary medical devices are used for a long time, the circuits in the screen will not change. In the case of intermittent work, a lot of heat will be generated, which will accelerate the aging of the display screen, and the clarity of the display screen will directly affect the doctor's diagnosis, so "accuracy" and "clearness" are essential attributes of medical display panels. [0003] The liquid crystal elastic constant is a physical quantity describing the elastic deformation of liquid crystal molecules, including the elastic constant K 1...
