Auto-orientation liquid crystal medium composition and liquid crystal display panel

Abstract

The invention provides an auto-orientation liquid crystal medium composition and a liquid crystal display panel. The auto-orientation liquid crystal medium composition comprises two or more additive materials which are selected from a first additive material and a second additive material, wherein the molecular structure of each of the first additive material and the second additive material consists of two parts, namely a head base and a tail base; the head base part of each of the first additive material and the second additive material has a main effect of being anchored on a base plate by virtue of intermolecular force, and the tail base part has a main effect similar to an effect of a PI branched chain to enable liquid crystal molecules to be arranged vertically in a way of steric hindrance; and by virtue of the collocation between different additive materials, the characteristic of easy aggregation of an additive material containing inorganic silicon groups can be improved, and the effect of anchoring a base plate of an additive material containing organic polar groups can be promoted.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a self-aligned liquid crystal medium composition and a liquid crystal display panel comprising the self-aligned liquid crystal medium composition. Background technique [0002] Thin Film Transistor Liquid Crystal Display (TFT-LCD, Thin Film Transistor Liquid Crystal Display) has many advantages such as thin body, power saving, and no radiation, and has been widely used. Most of the TFT-LCDs currently on the market are backlight liquid crystal display devices, which include a liquid crystal display panel and a backlight module. The working principle of the liquid crystal display panel is to place liquid crystal molecules between two parallel glass substrates, and control the liquid crystal molecules to change direction through whether the glass substrates are energized or not, and refract the light from the backlight module to produce a picture. [0003] Generally, a liquid crys...

AI Technical Summary

Problems solved by technology

[0005] At present, the above-mentioned additive materials mainly have two types: one is materials containing inorganic groups, such as octadecyl trichlorosilane, oligomer semisiloxane (POSS), etc. The solubility is poor, and it will be deposited on the surface of the substrate to achieve the effect of vertically aligning the liquid crystal, but it is easy to reunite itself, which will cause poor liquid crystal alignment and dark lines; the other is organic materials, such as: p-octyl aniline, N-heptanoic acid, etc., the main disadvantage of this type of material is that the anchoring effect on the substrate surface is weak, and when the concentration is low, the liquid crystal will cause light leakage.
