Embodiment 1

[0020] A liquid crystal composition comprising the following five weight percentages of liquid crystal monomer materials:

[0021] 20% of formula I, 35% of formula II, 20% of formula III, 20% of formula IV and 5% of formula V, wherein, in formula IV, R 1 and R of Formula V 2 Both are n-propyl.

Embodiment 2

[0023] A liquid crystal composition comprising the following five weight percentages of liquid crystal monomer materials:

[0024] 17.3% of formula I, 31.6% of formula II, 21.2% of formula III, 17.6% of formula IV and 12.3% of formula V, wherein, in formula IV, R 1 is n-pentyl, R of formula V 2 For n-butyl.

Embodiment 3

[0026] A liquid crystal composition comprising the following seven weight percentages of liquid crystal monomer materials:

[0027] 9.6% of formula I, 17.2% of formula II, 18.7% of formula III, 13.3% of formula IV(1), 18.4% of formula IV(2), 8.6% of formula V(1) and 14.2% of formula V (2), wherein, R in formula IV (1) 1 For n-propyl, R in formula IV (2) 1 For n-pentyl, the R of formula V(1) 2 Is ethyl, the R of formula V(2) 2 For n-propyl.

Abstract

The invention discloses a series of liquid crystal compositions, the series of liquid crystal compositions contain 5-7 kinds of single crystal materials, compared with the existing liquid crystal compositions, the invention provides a series of liquid crystal compositions with relatively few kinds of single crystal materials but different kinds of single crystal materials, the series of liquid crystal compositions have slight difference in performance under different proportions, but all the performances meet technical requirements.

Description

technical field [0001] The invention relates to a liquid crystal display material, in particular to a liquid crystal composition, which is formed by mixing 5-7 kinds of single crystals. Background technique [0002] The molecular structure of liquid crystal materials for displays generally has a rod-like or strip-like shape, and the six-membered ring containing benzene ring or cyclohexane is used as a hard core, and its performance is changed by replacing the hydrogen on the six-membered ring. The existing common The single crystal materials are all of the above-mentioned type. For example, patent EP0062470A1 discloses a benzene derivative liquid crystal, the hard core of which is connected by three six-membered rings and replaces para-hydrogen. Another example is the patent DE4111015 applied by Merck Company, which discloses a hard core structure in which three benzene rings are connected. It can be seen that the single crystal used in the existing liquid crystal composit...
